Spring service中怎么使用当前的service对象，Autowired不成功?报错

比如AuthServiceImpl下有getUser()和getPage()两个方法，在getPage中我要调用getUser()方法，使用

@Autowired(required = false)
private AuthService authService;

自动注入会报错，在getPage里面new一个AuthService对象也不可以。

像这种service中使用当前对象应该怎么注入？

代码如下：

第一种自动注入

public interface TestService {
   Integer getPage();
   Integer getUser();
}

@Service
public class TestServiceImpl implements TestService {
    @Autowired
    private TestService testService;
    @Override
    public Integer getPage() {
        Integer intGetUser=testService.getUser();
        return 1+intGetUser;
    }

    @Override
    public Integer getUser() {
        return 1;
    }
}

错误信息：

WARNING: Exception encountered during context initialization - cancelling refresh attempt
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'authServiceImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.seckill.service.AuthService org.seckill.service.impl.AuthServiceImpl.authService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.seckill.service.AuthService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

第二种：new对象

@Service
public class TestServiceImpl implements TestService {
   
    @Override
    public Integer getPage() {
        TestService testService=new TestServiceImpl();
        Integer intGetUser=testService.getUser();
        return 1+intGetUser;
    }

    @Override
    public Integer getUser() {
        return 1;
    }
}

错误信息：
