提问by Chaklader Asfak Arefe

I work on a Java/Spring/ Apache Cxfweb app and suddenly, I get the error while I made some apparently naive changes,

我在一个Java/Spring/ Apache Cxf网络应用程序上工作，突然间，当我做了一些明显天真的改变时，我收到了错误，

I guess this is the main infoof the error,

我想这是主要info的错误，

I would like to write a detailed answer on the issue and the steps I have followed to solve the problem.

我想写一个关于这个问题的详细答案以及我解决问题所遵循的步骤。

A. There was not enough logging info. I looked up the POMand found this,

A. 没有足够的日志信息。我查了一下POM，发现这个，

<dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>${spring.version}</version>
            <exclusions>
                <!-- Exclude Commons Logging in favor of SLF4j -->
                <exclusion>
                    <groupId>commons-logging</groupId>
                    <artifactId>commons-logging</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

I have excluded the logging in the favour of SLF4Jand I just deleted the exclusion XML tag to get more logging info. So, it becomes like this,

我已经排除了日志记录，SLF4J我只是删除了排除 XML 标记以获取更多日志记录信息。于是，就变成这样了

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>${spring.version}</version>
        </dependency>

B. Now, I get the logging info. I have this error message like,

B. 现在，我得到了日志信息。我有这样的错误信息，

Caused by: org.springframework.context.annotation.ConflictingBeanDefinitionException: Annotation-specified bean name 'userService' for bean class [mobi.puut.services.UserServiceImpl] conflicts with existing, non-compatible bean definition of same name and class [mobi.puut.services.UserService2Impl]

You get the ConflictingBeanDefinitionExceptionfor creating the bean with the same name. Though I have some experience with the Spring, I need to create with a project with the Apache Cxfand hence, clone a demo project for the very purpose. They have the one same entity Userand same definition - interfaceand same implementationof that. Though I have refactoredto all classes in the project and there seem no apparent errors, I still keep an issue - I keep the same bean name "userServicein 2 implementations of the interface.

您将获得ConflictingBeanDefinitionException用于创建具有相同名称的 bean。虽然我与一些经验Spring，我需要用一个项目创建Apache Cxf，因此，克隆演示为根本目的的项目。它们具有相同的实体，User并且相同definition - interface且相同implementation。尽管我必须refactored使用项目中的所有类并且似乎没有明显错误，但我仍然有一个问题 - 我"userService在接口的 2 个实现中保留了相同的 bean 名称。

The User2class in the entities,

User2实体中的类，

public class User2 {

    private Integer id;
    private String name;

    public User2() {
    }

    public User2(Integer id, String name) {
        this.id = id;
        this.name = name;
    }

    public String getName() {
        return name;
    }

    @Override
    public String toString() {
        return String.format("{id=%s,name=%s}", id, name);
    }
}

The Userclass in the entities,

User实体中的类，

    @Size(min = 5, max = 45, message = "Name must be between 5 and 45 characters.")
    private String name;

    public User() {

    }

    public User(int id, String name) {
        super();
        this.id = id;
        this.name = name;
    }

    public User(String name) {
        this.name = name;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (!(o instanceof User)) return false;

        User user = (User) o;

        if (getId() != user.getId()) return false;
        return getName().equals(user.getName());
    }

    @Override
    public int hashCode() {
        int result = getId();
        result = 31 * result + getName().hashCode();
        return result;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", name='" + name + '\'' +
                '}';
    }
}

The interfaces in the servicesdirectories,

services目录中的接口，

public interface IUserService2 {

    Collection<User2> getUsers();

    User2 getUser(Integer id);

    Response add(User2 user);
}



public interface IUserService {

    List<User> getCurrentStatuses();

    void create(User user);

    List<User> getAllUsers();
}

The implementations of the interfaces inside the servicesderectory,

目录中接口的services实现，

@Service("userService")
public class UserService2Impl implements IUserService2 {

    private static Map<Integer, User2> users = new HashMap<Integer, User2>();

    static {
        users.put(1, new User2(1, "foo"));
        users.put(2, new User2(2, "bar"));
        users.put(3, new User2(3, "baz"));
    }

    public UserService2Impl() {
    }

    @Override
    public Collection<User2> getUsers() {
        return users.values();
    }

    @Override
    public User2 getUser(Integer id) {
        return users.get(id);
    }

    @Override
    public Response add(User2 user) {
        user.setId(users.size()+1);
        users.put(user.getId(), user);

        //do more stuff to add user to the system..
        return Response.status(Response.Status.OK).build();
    }

}


@Service("userService")
public class UserServiceImpl implements IUserService {

    @Autowired
    @Qualifier("userDao")
    public IUserDao userDao;

    public List<User> getCurrentStatuses() {
        return userDao.getAllUsers();
    }

    public void create(User user) {
        userDao.saveOrUpdate(user);
    }

    public List<User> getAllUsers() {
        List<User> users = userDao.getAllUsers();

        if (Objects.isNull(users)) {
            return null;
        }
        return users;
    }
}

And, there was the error- I annotaed 2 classes with the same bean name of "userService". I had to change it like this to provide the bean a different name,

而且，有error- 我用相同的 bean 名称注释了 2 个类"userService"。我不得不像这样改变它来为 bean 提供一个不同的名称，

@Service("user2Service")
public class UserService2Impl implements IUserService2 {

    // some code
}

And, that error goes away. In short, the error ConflictingBeanDefinitionExceptiondue to the 2 beans of the same name and I just had to provide a different name.

而且，那个错误消失了。简而言之，错误是ConflictingBeanDefinitionException由于 2 个 bean 同名而我只需要提供不同的名称。

C. I still had things to fix. Afterwards, when I run the program, I get the

C. 我还有事情要解决。之后，当我运行程序时，我得到

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userService': Unsatisfied dependency expressed through field 'userDao'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'mobi.puut.database.IUserDao' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true), @org.springframework.beans.factory.annotation.Qualifier(value=userDao)}


// some consequent error messages not necessay to solve the issue

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'mobi.puut.database.IUserDao' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true), @org.springframework.beans.factory.annotation.Qualifier(value=userDao)}

The error here is UnsatisfiedDependencyExceptionand says it can't create a bean with the name of userService. OK, this is the code I had and integrated into the project. The Unsatisfied dependency expressed through the field namely userDao. userDaois the instance of the interface of IUserDaoand it was @autowiredlike this,

这里的错误是UnsatisfiedDependencyException说它不能创建一个名为userService. 好的，这是我拥有并集成到项目中的代码。通过字段表示的 Unsatisfied 依赖即userDao。userDao是接口的实例，IUserDao它是@autowired这样的，

    @Autowired
    public IUserDao userDao;

Here is more insight of the code,

这是代码的更多见解，

@Service("userService")
public class UserServiceImpl implements IUserService {

    @Autowired
    public IUserDao userDao;


     public List<User> getCurrentStatuses() {
        return userDao.getAllUsers();
    }

    public void create(User user) {
        userDao.saveOrUpdate(user);
    }

    public List<User> getAllUsers() {
        List<User> users = userDao.getAllUsers();

        if (Objects.isNull(users)) {
            return null;
        }
        return users;
    }
}

I have an interface in the databasedirectory and consequent implementation of the interface for the user. The interface name is IUserDaoand looks

我在database目录中有一个接口，随后为用户实现了该接口。接口名称是IUserDao和外观

soemthing like this, 


public interface IUserDao {

    boolean create(User user);

    void saveOrUpdate(User user);

    boolean create(List<User> users);

    List<User> getAllUsers();

    User getById(int id);
}

And, the implementation,

而且，实施，

@Repository("userDao")
public class UserDaoImpl implements IUserDao {

    @Autowired
    private SessionFactory sessionFactory;

    // the HQL queries

}

The consequent part of the error message was NoSuchBeanDefinitionExceptionand the app doesn't find a qualifying bean of the type (class) of IUserDao. I have all the HQLqueries in the implementation of the IUserDaoand the code works perfectly before.

错误消息的后续部分是NoSuchBeanDefinitionException，应用程序找不到IUserDao. 我HQL在实现中拥有所有查询，IUserDao并且代码之前运行良好。

I have to take a moment to think and finally, I have an intuition that may be the databaselayer is NOTintegrated into the app. Here is the configurationI used,

我不得不花点时间思考，最后，我有一个直觉，可能是该database层已NOT集成到应用程序中。这是configuration我使用的，

public class WebAppInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        servletContext.addListener(new ContextLoaderListener(createWebAppContext()));
        addApacheCxfServlet(servletContext);
    }

    private void addApacheCxfServlet(ServletContext servletContext) {
        CXFServlet cxfServlet = new CXFServlet();

        ServletRegistration.Dynamic appServlet = servletContext.addServlet("CXFServlet", cxfServlet);
        appServlet.setLoadOnStartup(1);

        Set<String> mappingConflicts = appServlet.addMapping(AppConfig.API_BASE);
    }

    private WebApplicationContext createWebAppContext() {
        AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext();

        // register all the config classes here
        appContext.register(AppConfig.class);
        return appContext;
    }

}

Obviously, the no database code is integrated in the WebInitializer. I wrote a new class provides all the info of the database connectionand the hibernate integrationand looks like,

显然，没有数据库代码集成在WebInitializer. 我写了一个新类，提供了database connection和 的所有信息，hibernate integration看起来像，

@Configuration
@EnableWebMvc
@EnableTransactionManagement
@ComponentScan(basePackages = {"mobi.puut.database"})
public class DatabaseConfig {

    @Bean
    public LocalSessionFactoryBean sessionFactory() {

        //  mobi.puut.entities
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan(
                new String[]{"mobi.puut.entities"});
        sessionFactory.setHibernateProperties(hibernateProperties());

        return sessionFactory;
    }

    @Bean
    @Autowired
    public HibernateTransactionManager transactionManager(
            SessionFactory sessionFactory) {

        HibernateTransactionManager txManager
                = new HibernateTransactionManager();
        txManager.setSessionFactory(sessionFactory);

        return txManager;
    }

    @Bean
    public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
        return new PersistenceExceptionTranslationPostProcessor();
    }

    @Bean
    public DataSource dataSource() {

        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");

        // dataSource.setUrl("jdbc:mysql://localhost:3306/wallet?createDatabaseIfNotExist=true");
        dataSource.setUrl("jdbc:mysql://localhost:3306/Wallet");
        dataSource.setUsername("testuser");
        dataSource.setPassword("testpassword");

        return dataSource;
    }

    Properties hibernateProperties() {

        Properties properties = new Properties();
//        properties.setProperty("hibernate.hbm2ddl.auto", "create-drop");
        properties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect");
        return properties;
    }
}

And, then finally integrate into the WebInitializer. This is the code I used to registeredthe config earlier in the WebInitializer,

并且，然后最终融入到WebInitializer. 这是我之前用于registered配置的代码WebInitializer，

appContext.register(AppConfig.class);

Updated the line with the,

更新了行，

appContext.register(AppConfig.class, DatabaseConfig.class);

Finally, everything works fine. So, the configdirectory looks like,

最后，一切正常。所以，config目录看起来像，

SUMMERY

SUMMERY

I had to solve this problem through the 3 errors,

我不得不通过 3 个错误来解决这个问题，

i. ConflictingBeanDefinitionException
ii. UnsatisfiedDependencyException
iii. NoSuchBeanDefinitionException

ConflictingBeanDefinitionException-> 2 beans with the same name

ConflictingBeanDefinitionException-> 2 个同名豆子

UnsatisfiedDependencyException-> Have a bean (= "userDao")in the class which was not correct to use

UnsatisfiedDependencyException-> 类中有一个(= "userDao")不正确使用的 bean

NoSuchBeanDefinitionException-> the code was correct but needed to add the datbase layer in the congig so the Spring IoCfinds the bean.

NoSuchBeanDefinitionException-> 代码是正确的，但需要在配置中添加 datbase 层，以便Spring IoC找到 bean。

I sincerely hope this will help some people.

我真诚地希望这会帮助一些人。
