Spring boot failing to start rest service
提问by Sivasakthi Jayaraman
I tried to simulate the RESTful Web Service from the spring home page "https://spring.io/guides/gs/rest-service/". I am able to get the expected output for the given example, so i did a little enhancement i.e tried to fetch some count from the oracle database and display as part of response but it didn't work.
我尝试从 spring 主页“ https://spring.io/guides/gs/rest-service/”模拟 RESTful Web Service 。我能够获得给定示例的预期输出，所以我做了一些改进，即尝试从 oracle 数据库中获取一些计数并作为响应的一部分显示，但它没有工作。
Maven compilation works fine but when i run the spring boot i am getting the below error, i don't know what could be the reason. I am new to spring, can someone help me?

If you are using spring-boot, add the dependency below in order to use autoconfiguration
如果您使用的是 spring-boot，请添加以下依赖项以使用自动配置
pom.xml
pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
In your application.properties
在您的 application.properties 中
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@testserver.com:2126:QADBA9FU
spring.datasource.username=test
spring.datasource.password=password123

Remove this in yout EmployeeController
在你的 EmployeeController 中删除它
ApplicationContext ctx = new FileSystemXmlApplicationContext("/Users/sijayaraman/Documents/workspace/luna/CopyofSpringRest/sbeans.xml");
EmployeeDao dao=(EmployeeDaoImpl)ctx.getBean("employeedao");
instead use
而是使用
@Autowired
private EmployeeDao dao;
Also, annotate class
另外，注释类
@Component
public class EmployeeDaoImpl ...

It might not be the root of your problem, but you are not accessing your dao correctly. The main principle of Spring is Dependency Injection, which means Controllershould not be getting it's DAO. Instead it should be either autowired or set in the config file.
它可能不是您问题的根源，但您没有正确访问您的 dao。Spring 的主要原则是依赖注入，这意味着Controller不应该获取它的 DAO。相反，它应该自动装配或在配置文件中设置。
Then you Controllerwould look like this:
然后你Controller看起来像这样：
@RestController
public class EmployeeController {
@Autowired
EmployeeDao dao;
@RequestMapping("/employee")
public Employee employee(@RequestParam(value="name") String name) {
System.out.println("Count="+dao.getTotalCount());
return new Employee(dao.getTotalCount(),name);
}
}
You will need to add the sbeans.xmlto the configuration. Try adding
@ImportXml("classpath:sbeans.xml")to Application.java:
您需要sbeans.xml在配置中添加。尝试添加
@ImportXml("classpath:sbeans.xml")到Application.java：
@SpringBootApplication
@ImportXml("classpath:sbeans.xml")
public class Application
or better yet rewrite sbeans.xmlin Java.
或者更好的是sbeans.xml用 Java重写。
