java - 如何在 Spring MVC 2.5 项目中使用 MockMvc？

Question

MockMvc是在Spring Test 3.2中引入的。我有一个依赖 Spring MVC 2.5 的旧项目，它很难升级(有太多的事情需要解决)。我想使用 MockMvc 进行集成测试。

代码如下:

import static org.hamcrest.CoreMatchers.containsString;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

import java.io.IOException;

import org.junit.AfterClass;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import redis.embedded.RedisServer;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/afdspplicationContext*.xml",
        "/applicationContext*.xml"})
@WebAppConfiguration
public class ScheduleControllerTest {
    private static RedisServer redisServer;
    @Autowired
    private WebApplicationContext wac;

    private MockMvc mockMvc;
    @BeforeClass
    public static void setUp() throws IOException {

        redisServer = new RedisServer(45678);
        redisServer.start();
    }

    @Before
    public void setup() throws Exception {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
    }

    @AfterClass
    public static void tearDown() {
        redisServer.stop();
    }
    @Test
    public void getRoomStatusByDateAndBuilding() throws Exception {

        this.mockMvc.perform(get("/api/v1/recommend/checkin?userName=dd&roomName=f"))
                .andExpect(status().isOk())
                .andExpect(content().string(containsString("\"code\":422")))
                .andExpect(content().string(containsString("test")));
    }
}

但是，测试最终出现错误:

objc[77723]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home/bin/java (0x10bc614c0) and /Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x10bcd14e0). One of the two will be used. Which one is undefined.

可能出现此错误是因为 Spring MVC 2.5 与 Spring Test 4.3.9 不匹配。是否存在任何解决方法，让我在继续使用 Spring MVC 2.5 的同时使用 MockMvc？

Answer 1

Spring 2.5 于 11 年前(2007 年 11 月 19 日)发布，并未正式支持您尝试使用的 Java 7。根据Spring Framework 2.5 Released :

• Full Java 6 and Java EE 5 support (JDBC 4.0, JTA 1.1, JavaMail 1.4, JAX-WS 2.0)

您正在运行一个非常不寻常且容易出错的设置。升级 Spring 或自行重新创建和反向移植 MockMvc 框架，然后降级到 Java 6。不要混合 2.5 和 3.2 依赖项，这会产生很多类路径问题，就像您刚刚观察到的那样。

我认为 11 年后升级 Spring 并不是开发人员最糟糕的时间投资。
