Question

我想要创建Rest Web Services并且它起作用了。我更改了代码，现在我有这个错误：

org.springframework.beans.factory.UnsatisfiedDependencyException：在文件中定义名称为“ controllery”的bean创建时出错 [C：\ Users \ amir \ workspace \ gu \ target \ classes \ gu \ webservice \ controller \

听是我的控制器类：

@Controller
@RequestMapping("/start")
public class Controllery {
    //private static final org.jboss.logging.Logger logger = LoggerFactory.logger(Controllery.class);
    @Autowired
    Services test;
    public Controllery(Services test) {
        //super();
        this.test = test;
    }

    @PostMapping
    public List<Test> customercontroll(){
        return test.findAllTest();
    }
     @PostMapping("/employees")
        public Test createEmployee(@Valid @RequestBody Test employee) {
            return test.SaveTest(employee);
        }

我的存储库界面：

@Service
public interface TestRepository extends  JpaRepository<Test ,Long> {

    Test findByLastname();
}

我的服务等级：

package gu.webservice.impl;
import java.util.List;
import org.springframework.stereotype.Service;
import gu.webservice.domain.Test;
@Service
public interface Services{
    Test findTestById(Long id);
    List<Test>findAllTest();
    Test SaveTest(Test test);
    //Test findTestByLastName();
}
And Service impl:
package gu.webservice.impl;

import java.util.List;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import gu.webservice.domain.Test;
import gu.webservice.repository.TestRepository;
@Configuration
@EnableWebMvc //THIS
@ComponentScan(basePackages = "guru.services")

public  class InterfaceImpl implements Services{
    TestRepository test;
    Test entity;
    public InterfaceImpl(TestRepository test) {
    //  super();
        this.test = test;
    }

    /*@Override
    public Test findTestById(Long id) {
        // TODO Auto-generated method stub
        return test.getOne(id);
    }
*/
    @Override
    public List<Test> findAllTest() {
        // TODO Auto-generated method stub
        return (List<Test>) test.findAll();
    }

    public Test SaveTest(Test test) {
        // TODO Auto-generated method stub
        return this.test.save(test);
    }
/*
    @Override
    public Test findTestByLastName() {
        // TODO Auto-generated method stub
        return test.findByLastname();
    }
*/
    @Override
    public Test findTestById(Long id) {
        // TODO Auto-generated method stub
        return null;
    }
}

引导程序类：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import gu.webservice.domain.Test;
import gu.webservice.repository.TestRepository;
public class TestBootstrap implements CommandLineRunner {
    @Autowired
    TestRepository test;
    public TestBootstrap(TestRepository test){
        this.test=test;
    }
    @Override
    public void run(String... args) throws Exception {
        // TODO Auto-generated method stub
        Test t=new Test();
        t.setId(1);
        t.setName("ali");
        t.setLastname("rezaii");
        test.save(t);

    }

}

有人可以帮助我解决问题吗？

已编辑：在存储库中，将@Service更改为@Repository

在您的InterfaceImpl.java中，您需要向服务中注入@Autowired。

必须是这样的：

@Configuration
@EnableWebMvc //THIS
@ComponentScan(basePackages = "guru.services")

public  class InterfaceImpl implements Services{

@Autowired
TestRepository test;
Test entity;

// ADD GETTERS AND SETTERS OF test

public InterfaceImpl() {
super();
}
// ALL METHODS HERE
}
