Spring boot AngularJS示例
在本教程中,我们将看到如何创建Spring Boot AngularJS示例。
我们将使用Spring Boot 1.5.3发布版本,它配有Hibernate 5.
我们将创建一个Spring Boot AngularJS应用程序,它将具有AngularJS作为用户界面。
它将提供用户界面,我们可以从中添加,更新或者删除客户数据库。
我们将使用控制器,服务和DAO类来实现这些功能。
我们将使用SessionFactory类Hibernate连接到MySQL数据库。
用于创建以下项目的工具:
- Spring boot 1.5.3.Release.
- Spring4.3.8.Release.
- Tomcat Embed 8.
- Maven 3.
- Java 8.
- Eclipse
- Hibernate 5.3.5.
- mysql 5.7.18
第1步:使用名为"springboottangularjsexample"的Eclipse中的Maven创建动态Web项目。
第2步:更改"pom.xml"如下:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>org.igi.theitroad</groupId> <artifactId>SpringBootHibernateExample</artifactId> <version>0.0.1-SNAPSHOT</version> <name>SpringBootHibernateExample Maven Webapp</name> <url>http://maven.apache.org</url> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.3.RELEASE</version> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <!-- JSTL for JSP --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> </dependency> <!-- For JSP compilation --> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-jasper</artifactId> <scope>provided</scope> </dependency> <!-- https://mvnrepository.com/artifact/org.threeten/threetenbp --> <dependency> <groupId>org.threeten</groupId> <artifactId>threetenbp</artifactId> <version>0.7.2</version> </dependency> </dependencies> <build> <finalName>SpringBootHibernateExample</finalName> </build> </project>
Spring-Boot-Starter-Parent为我们提供任何Spring项目所需的所有Maven默认值。
由于我们正在开发Web应用程序,我们还需要添加Spring-Boot-Starter-Web依赖项,并且我们还需要包含Pring-Boot-Starter-Data-JPA以将此应用程序运行Hibernate。
我们还需要将MySQL-Connector-Java放入MySQL JDBC驱动程序。
如果我们使用的是任何其他数据库,则需要使用不同的数据库连接器。
让我们首先进行Hibernate配置。
Hibernate配置
第3步:在Package .org.igi.theitroad中创建名为"hibernateConfiguration.java"的文件
package org.igi.theitroad;
import java.util.Properties;
import javax.sql.DataSource;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.hibernate5.HibernateTransactionManager;
import org.springframework.orm.hibernate5.LocalSessionFactoryBean;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;
import org.springframework.transaction.annotation.EnableTransactionManagement;
@Configuration
@EnableTransactionManagement
public class HibernateConfiguration {
@Value("${db.driver}")
private String DRIVER;
@Value("${db.password}")
private String PASSWORD;
@Value("${db.url}")
private String URL;
@Value("${db.username}")
private String USERNAME;
@Value("${hibernate.dialect}")
private String DIALECT;
@Value("${hibernate.show_sql}")
private String SHOW_SQL;
@Value("${hibernate.hbm2ddl.auto}")
private String HBM2DDL_AUTO;
@Value("${entitymanager.packagesToScan}")
private String PACKAGES_TO_SCAN;
@Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(DRIVER);
dataSource.setUrl(URL);
dataSource.setUsername(USERNAME);
dataSource.setPassword(PASSWORD);
return dataSource;
}
@Bean
public LocalSessionFactoryBean sessionFactory() {
LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
sessionFactory.setDataSource(dataSource());
sessionFactory.setPackagesToScan(PACKAGES_TO_SCAN);
Properties hibernateProperties = new Properties();
hibernateProperties.put("hibernate.dialect", DIALECT);
hibernateProperties.put("hibernate.show_sql", SHOW_SQL);
hibernateProperties.put("hibernate.hbm2ddl.auto", HBM2DDL_AUTO);
sessionFactory.setHibernateProperties(hibernateProperties);
return sessionFactory;
}
@Bean
public HibernateTransactionManager transactionManager() {
HibernateTransactionManager transactionManager = new HibernateTransactionManager();
transactionManager.setSessionFactory(sessionFactory().getObject());
return transactionManager;
}
}
上面的类是用@configuration和@bean注释注释。
这些注释用于在Spring 中定义 Bean。
@Configuration类似于<bean>标记在Spring XML配置中,@Bean类似于<bean>标记。
@Value注释用于从属性文件注入变量。
在这种情况下,它将从Application.properties中读取,我们将在下一步中创建。
第4步:在包/src/main /资源中创建名为"application.properties"的文件
logging.level=DEBUG # Database db.driver: com.mysql.jdbc.Driver db.url: jdbc:mysql://localhost:3306/CustomerData db.username: root db.password: admin # Hibernate hibernate.dialect: org.hibernate.dialect.MySQL5Dialect hibernate.show_sql: true hibernate.hbm2ddl.auto: create entitymanager.packagesToScan: org spring.jpa.properties.hibernate.enable_lazy_load_no_trans=true
模型类
第5步:在Package .org.igi.theitroad.model中创建名为"customer.java"的文件
package org.igi.theitroad.model;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
/*
* This is our model class and it corresponds to Customer table in database
*/
@Entity
@Table(name="CUSTOMER")
public class Customer{
@Id
@Column(name="id")
@GeneratedValue(strategy=GenerationType.IDENTITY)
int id;
@Column(name="customerName")
String customerName;
@Column(name="email")
String email;
public Customer() {
super();
}
public Customer(String customerName,String email) {
super();
this.customerName=customerName;
this.email=email;
}
public String getCustomerName() {
return customerName;
}
public void setCustomerName(String customerName) {
this.customerName = customerName;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
}
@entity用于制作持久的POJO类。
对于此Java类,我们将在数据库中具有相应的表。
@column用于将注释属性映射到表中的相应列。
创建客户表:
使用以下DDL在数据库中创建客户表。
CREATE TABLE CUSTOMER ( id int(11) NOT NULL AUTO_INCREMENT, customerName varchar(255) DEFAULT NULL, email varchar(255) DEFAULT NULL, PRIMARY KEY (id) )
控制器类
第6步:在包中创建一个名为"customercontroller.java"的文件.igi.theitroad.Controller
package org.igi.theitroad.controller;
import java.util.List;
import org.igi.theitroad.model.Customer;
import org.igi.theitroad.service.CustomerService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class CustomerController {
@Autowired
CustomerService customerService;
@RequestMapping(value = "/getAllCustomers", method = RequestMethod.GET, headers = "Accept=application/json")
public List<Customer> getAllCustomers(Model model) {
List<Customer> listOfCustomers = customerService.getAllCustomers();
model.addAttribute("customer", new Customer());
model.addAttribute("listOfCustomers", listOfCustomers);
return listOfCustomers;
}
@RequestMapping(value = "/", method = RequestMethod.GET, headers = "Accept=application/json")
public String goToHomePage() {
return "redirect:/getAllCustomers";
}
@RequestMapping(value = "/getCustomer/{id}", method = RequestMethod.GET, headers = "Accept=application/json")
public void getCustomerById(@PathVariable int id) {
customerService.getCustomer(id);
}
@RequestMapping(value = "/addCustomer", method = RequestMethod.POST, headers = "Accept=application/json")
public Customer addCustomer(@RequestBody Customer customer) {
return customerService.addCustomer(customer);
}
@RequestMapping(value = "/addCustomer", method = RequestMethod.PUT, headers = "Accept=application/json")
public Customer updateCustomer(@RequestBody Customer customer) {
return customerService.updateCustomer(customer);
}
@RequestMapping(value = "/deleteCustomer/{id}", method = RequestMethod.DELETE, headers = "Accept=application/json")
public void deleteCustomer(@PathVariable("id") int id) {
customerService.deleteCustomer(id);
}
}
服务层
第7步:在Package .org.igi.theitroad.service中创建名为"customereservice.java"的文件
package org.igi.theitroad.service;
import java.util.List;
import javax.transaction.Transactional;
import org.igi.theitroad.dao.CustomerDao;
import org.igi.theitroad.model.Customer;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service("customerService")
public class CustomerService {
@Autowired
CustomerDao customerDao;
@Transactional
public List<Customer> getAllCustomers() {
return customerDao.getAllCustomers();
}
@Transactional
public Customer getCustomer(int id) {
return customerDao.getCustomer(id);
}
@Transactional
public Customer addCustomer(Customer customer) {
customerDao.addCustomer(customer);
return customer;
}
@Transactional
public Customer updateCustomer(Customer customer) {
customerDao.updateCustomer(customer);
return customer;
}
@Transactional
public void deleteCustomer(int id) {
customerDao.deleteCustomer(id);
}
}
DAO层
第8步:在Package .org.igi.theitroad.dao中创建名为"customerdao.java"的接口
package org.igi.theitroad.dao;
import java.util.List;
import org.igi.theitroad.springboot.Customer;
public interface CustomerDao {
public List<Customer> getAllCustomers() ;
public Customer getCustomer(int id) ;
public Customer addCustomer(Customer customer);
public void updateCustomer(Customer customer) ;
public void deleteCustomer(int id) ;
}
步骤9:在包中创建名为"customerdaoimpl.java"的文件.igi.theitroad.dao
package org.igi.theitroad.dao;
import java.util.List;
import org.igi.theitroad.model.Customer;
import org.hibernate.Hibernate;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
@Repository
public class CustomerDaoImpl implements CustomerDao{
@Autowired
private SessionFactory sessionFactory;
public void setSessionFactory(SessionFactory sf) {
this.sessionFactory = sf;
}
public List<Customer> getAllCustomers() {
Session session = this.sessionFactory.getCurrentSession();
List<Customer> customerList = session.createQuery("from Customer").list();
return customerList;
}
public Customer getCustomer(int id) {
Session session = this.sessionFactory.getCurrentSession();
Customer customer = (Customer) session.get(Customer.class, id);
return customer;
}
public Customer addCustomer(Customer customer) {
Session session = this.sessionFactory.getCurrentSession();
session.save(customer);
return customer;
}
public void updateCustomer(Customer customer) {
Session session = this.sessionFactory.getCurrentSession();
session.update(customer);
}
public void deleteCustomer(int id) {
Session session = this.sessionFactory.getCurrentSession();
Customer p = (Customer) session.load(Customer.class, new Integer(id));
if (null != p) {
session.delete(p);
}
}
}
AngularJS View.
步骤10:在包中创建名为"customerDataAngularjs.html"的文件.src.main.webapp
<html>
<head>
<script
src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.4/angular.js"></script>
<title>Spring Boot AngularJS example</title>
<script type="text/javascript">
var app = angular.module("CustomerManagement", []);
//Controller Part
app.controller("CustomerController", function($scope, $http) {
$scope.customers = [];
$scope.customerForm = {
id : -1,
customerName : "",
email : ""
};
//Now load the data from server
_refreshCustomerData();
//HTTP POST/PUT methods for add/edit customer
//with the help of id, we are going to find out whether it is put or post operation
$scope.submitCustomer = function() {
var method = "";
var url = "";
if ($scope.customerForm.id == -1) {
//Id is absent in form data, it is create new customer operation
method = "POST";
url = '/addCustomer';
} else {

method = "PUT";
url = '/addCustomer';
}
$http({
method : method,
url : url,
data : angular.toJson($scope.customerForm),
headers : {
'Content-Type' : 'application/json'
}
}).then( _success, _error );
};
//HTTP DELETE- delete customer by Id
$scope.deleteCustomer = function(customer) {
$http({
method : 'DELETE',
url : '/deleteCustomer/' + customer.id
}).then(_success, _error);
};
//In case of edit, populate form fields and assign form.id with customer id
$scope.editCustomer = function(customer) {
$scope.customerForm.customerName = customer.customerName;
$scope.customerForm.email = customer.email;
$scope.customerForm.id = customer.id;
};
/* Private Methods */
//HTTP GET- get all customers collection
function _refreshCustomerData() {
$http({
method : 'GET',
url : 'http://localhost:8080/getAllCustomers'
}).then(function successCallback(response) {
$scope.customers = response.data;
}, function errorCallback(response) {
console.log(response.statusText);
});
}
function _success(response) {
_refreshCustomerData();
_clearFormData()
}
function _error(response) {
console.log(response.statusText);
}
//Clear the form
function _clearFormData() {
$scope.customerForm.id = -1;
$scope.customerForm.customerName = "";
$scope.customerForm.email = "";
};
});

解释 :
- 我们已经注入$HTTP,因为我们通过控制器构造函数在Ajax示例中完成了$HTTP。
app.controller("CustomerController", function($scope, $http) {
$scope.customers = [];
...
- 我们已经定义了各种方法,具体取决于EditCustomer,Deletecustomer,SubmitCustomer等操作
- 单击表单上的"提交"按钮时,它实际上会根据操作调用帖子或者放置。如果我们单击"编辑"并提交数据,那么它将被按照现有资源更新。如果直接提交数据,那么它将是创建新资源的发布操作,
- 每次提交数据时,它都会调用引用COSTOMERDATA()来刷新下面的客户表。
- 当我们调用$HTTP时,我们需要通过方法类型和URL,它将根据Web应用程序的上下文根目录放置绝对URL或者相对URL。
//HTTP GET- get all customers collection
function _refreshCustomerData() {
$http({
method : 'GET',
url : 'http://localhost:8080/getAllCustomers'
}).then(function successCallback(response) {
$scope.customers = response.data;
}, function errorCallback(response) {
console.log(response.statusText);
});
}
}
Spring boot 主文件
步骤11:在Package .org.igi.theitroad中创建名为"springboottangularjsapplication.java"的文件
package org.igi.theitroad;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringBootAngularJSApplication {
public static void main(String[] args)
{
SpringApplication.run(SpringBootAngularJSApplication.class, args);
}
}
我们刚刚添加了@springbootapplication,它做了所有的工作。
让我们了解更多关于这个注释的信息。
@springBootApplication是添加以下所有内容的注释:
@configuration使类作为应用程序上下文的Bean定义的源。
@EnableAutoConfiguration允许Spring Boot在ClassPath设置和各种属性设置中添加Bean礼物。
通常,我们将为Spring MVC应用程序添加@bableWebMVC,但Spring Boot会在类路径上看到Spring-WebMVC时自动添加它。
将应用程序标记为Web应用程序,并激活诸如设置DispatcherServlet之类的关键行为。
@ComponentsCan告诉Spring在默认包中查找其他组件,配置和服务,允许它找到控制器。
如果未定义特定包,则会从声明此注释的类的包中扫描。
运行应用程序
第12步:是时候制造了maven的时候了。
右键单击项目 - >运行AS - > Maven Build
步骤13:提供单击清洁安装的目标:运行(下面给出)并单击"运行"
步骤14:使用Maven Build完成后,让我们转到浏览器并置于URL之后。
http://localhost:8080/customerdataangularjs.html
添加以下详细信息到客户名称:作为"John"和电子邮件作为"[email protected]",然后单击提交。
现在我正在使用上述方法添加更多客户。
让我们单击与客户ID对应的编辑链接:3,其中名称为David。
我正在更改"[email protected]"的电子邮件地址到"[email protected]"
单击"提交"时,我们将看到以下屏幕。
正如我们可以看到David的电子邮件地址已更改为"更改@ gmail.com"。
让我们点击与客户ID相对应的删除链接:2姓名是Martin,我们将看到下面的屏幕。
正如我们所看到的,Martin已从列表中删除。
