如何@autowire 实现在 xml 文件中的接口（Jersey + Spring）

Question

我使用的是 Jersey + Spring，我有一个 Mapper 接口，它的实现是在包含查询的 xml 中。 @Autowired 注释在 spring 控制器中工作正常，但它不接受 Jersey 中的 @Autowired 并说没有为此注册 bean。我怎样才能让它在 Jersey Resource 类中像在 Spring Controller 中一样工作？

EmployMapper 界面

package com.resource.mapper;
import java.util.ArrayList;
import org.apache.ibatis.annotations.Param;


public interface EmployMapper {
    public int addUser(@Param("name") String name);

}

EmployMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
  PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.resource.mapper.EmployMapper">
     <update id="addUser" > 
    insert INTO mytable (name) VALUES(#{name}); 
    </update>
</mapper>

弹簧控制器

package com.controller;

@Controller
public class EmployController {
    @Autowired
    EmployMapper employMapper;

    @RequestMapping("test")
    public ModelAndView reviewspage()
    {
        employMapper.addUser("SpringMVC");
          ModelAndView modelAndView = new ModelAndView("test");         
            return modelAndView;
    }
}

球衣资源

package com.resource;

@Component
@Path("/e")
public class MyResource {
    @Autowired
    EmployMapper mapper;
    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String getEmployees(){
        mapper.addUser("Done it");
        return "Biggest succcess of the year";
    }
}

web.xml

 </bean>

</bean>

</beans>

这里 @Autowired 不工作并说 bean 没有找到任何匹配项

错误

org.springframework.beans.factory.BeanCreationException：创建名为“myResource”的bean时出错：注入自动装配的依赖项失败；嵌套异常是 org.springframework.beans.factory.BeanCreationException：无法自动装配字段：com.resource.mapper.EmployMapper com.resource.MyResource.mapper；嵌套异常是 org.springframework.beans.factory.NoSuchBeanDefinitionException：没有为依赖项找到类型为 [com.resource.mapper.EmployMapper] 的匹配 bean：预计至少有 1 个 bean 有资格作为此依赖项的自动装配候选者。依赖注解：{@org.springframework.beans.factory.annotation.Autowired(required=true)}

试试这个solution 让 Jersey 能够使用 Spring bean
