Question

我想通过JPA @Entity自动添加一个通过@Component/@Resource/@Configurable注释的类，所以我添加了Spring的@Component @Entity @Table public class Employee{ @Autowired TestService testService; ... }注释，但它不允许我自动加载该类。

是否需要其他注释？。

示例是：

TestService

使用@Service注释班级$("#cols").on('mouseenter',cols,function(){ cols.resizable({ maxHeight: 20, minHeight: 20, distance: 5, handles: 'e', start: function() { console.log("I've started!"); }, stop: function() { console.log("I've stopped!"); } }); });。

Answer 1

您可以轻松地执行此操作，创建构造函数并将注入的Service作为参数传递：

@Component
@Entity
@Table
public class Employee{

    Employee(TestService testService){

        //Do some work      
    }
   ...
}

现在调用者类..

@Service
public class CallerClass{

   @Autowired   
   TestService testService;

   Employee employee =new Employee(testService);
}

Answer 2

您需要使用@Configurable

@Entity
@Table
@Configurable
public class Employee{

   @Autowired
   TestService testService;
   ...
}

在JPA @Entity和Spring @ Component / @ Resource / @ Configurable之间发生冲突
