Question

我正在使用RestAssuredMockMvc测试一个休息控制器。这是我的代码

/*Repository*/
package com.rest.api.repository;

import java.util.List;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.querydsl.QueryDslPredicateExecutor;
import org.springframework.stereotype.Repository;
import com.mysema.query.types.Predicate;

@Repository
public interface ClientRepository extends JpaRepository<Client, Long>,
    QueryDslPredicateExecutor<Client> {

    Client findByClientId(Integer clientId);
    Client findOne(Predicate predicate);
    List<Client> findAll(Predicate predicate);
}

/*Services to be offered*/   
package com.rest.api.service;

import java.util.List;
import com.mysema.query.types.Predicate;
import com.rest.api.model.Client;
import com.rest.api.repository.ClientRepository;

public interface ClientService {
    Boolean saveEnterprise(Client client, ClientRepository clientRepository);
}

/*Implementation*/
package com.rest.api.service.implementations;

import java.util.ArrayList;
import java.util.List;
import org.springframework.stereotype.Service;
import com.google.common.collect.Lists;
import com.mysema.query.types.Predicate;
import com.rest.api.logging.LoggingManager;
import com.rest.api.model.Client;
import com.rest.api.repository.ClientRepository;
import com.rest.api.service.ClientService;

@Service
public class ClientImpl implements ClientService {

    @Override
    public Boolean saveEnterprise(Client client,
            ClientRepository clientRepository) {
        try {
            LoggingManager.info(getClass(), "CLIENT="+client);
            if(clientRepository == null){
                LoggingManager.info(getClass(), "CLIENT REPO NULL");
            }
            if (client != null) {
                clientRepository.save(client);
            }
        } catch (Exception e) {
            LoggingManager.debug(getClass(),
                        "Error while saving assistance details");
            e.printStackTrace();
            return false;
        }
        return true;
    }
}

/* CONTROLLER*/
@Controller
public class ClientController {
    @Autowired
    ClientRepository clientRepository;

    @Inject
        public void setRepository(ClientRepository clientRepository) {
            this.clientRepository = clientRepository;
    }

    // Get Service Handle - A Singleton 
    private ClientService enterpriseServicehandle = EnterpriseClient
        .getInstance().getEnterpriseService();

    @RequestMapping(value = ApiEndpointConstants.CREATE_NEW_CLIENT, method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE, headers = "content-type=application/x-www-form-urlencoded")
    @ResponseBody
    public EnterpriseResponse saveEnterprise(@RequestBody Client client) {

        EnterpriseResponse enterpriseResponse = new EnterpriseResponse();
        enterpriseServicehandle.saveEnterprise(client, clientRepository);

        enterpriseResponse.setEnterprise(client);
        enterpriseResponse
                .setResponseCode(212);
        enterpriseResponse
                .setResponseMessage("Client creation Successful");

        return enterpriseResponse;
    }
}

/* Test Class*/
import static com.jayway.restassured.module.mockmvc.RestAssuredMockMvc.*;
import junit.framework.Assert;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;

public class ClientControllerTest {

    @Autowired
    private ClientRepository clientRepository;

    @Autowired
    private WebApplicationContext webApplicationContext;

    @Autowired
    private AccesscodeRepository accesscodeRepository;

    @Before
    public void setUp() throws Exception {
    }

    @After
    public void tearDown() throws Exception {
    }

    @Test
    public final void testFunctionality() {

         String clientJson = "{\"name\":\"Client1\",\"clientId\":1000,\"fromEmailAddress\":\"goutham@atreya.in\"}";

         MockMvcResponse clientCreationResponse = given()
             .standaloneSetup(new ClientController())
                    .body(clientJson)
                 .contentType(ContentType.JSON)
             .when()
                 .post("api/client/save")
             .then()
                 .statusCode(200)
                .extract().response();

         System.out.println(clientCreationResponse.asString());
         Integer clientResponseCode = clientCreationResponse.path("responseCode");
         String clientResponseMessage = clientCreationResponse.path("responseMessage");
         System.out.println("INT:" + clientResponseCode);
         Assert.assertEquals(clientResponseCode, 211);
         Assert.assertEquals(clientResponseMessage,"Client Creation Successful");       
    }
}

当我运行测试用例时，我收到此错误（请注意， clientRepository为NULL 并抛出NPE，但最后一行表明客户端已成功创建。，

有人可以指导我吗？我究竟做错了什么？为什么我的存储库为空？
当我使用Curl命令和测试时，端点确实有效，但是，我无法为单元测试编写junit，请帮忙

我遇到了完全相同的问题。当我运行该项目时，它工作正常。但是当我测试控制器时，一些自动装配的变量变为空，这使测试失败。

在我的代码中，我有一个userWebController执行“注册”工作。还有另一个类CustomedUserDetailsService，它与JdbcTemplate对象一起使用，以将新用户添加到数据库。 JdbcTemplate对象使用bean自动装配。当我测试控制器时，这个JdbcTemplate对象为null，这意味着它没有注入成功。

我尝试了以下方法（jdbc bean在类OnlineDBConfig中定义），但不起作用：

@ContextConfiguration( classes = {OnlineDBConfig.class})

我用以下解决方案解决了我的问题： 1，直接将failed_autowired对象移动到Test类（StandaloneUserControllerTest） 2，将对象传递给使用它的控制器类。

以下是最终的测试课程：

public class StandaloneUserControllerTest extends AbstractSpringJunit4Tests { @Autowired @Qualifier("jdbcOnline") protected JdbcTemplate jdbc; @Before public void before(){ RestAssuredMockMvc.standaloneSetup(new UserWebController(jdbc) ) ; if( jdbc == null ) fail("autowired failed again") ; } }

这很糟糕，但它确实有效。希望能有更好的解决方案。
