java - 启用 webmvc 时，基于 Spring Java 的配置和 JUnit 不起作用

Question

我已经开始使用一个新的基于 Spring 3.2.0.RELEASE 的应用程序，我真的很想取消 XML 配置，因为它是一个新项目，但是当涉及到它时我遇到了困难编写 Junit 测试。

这里是java配置(WebConfig.java): 包 com.myapp.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

@Configuration
@EnableWebMvc
@ComponentScan("com.myapp.controllers")
public class WebConfig{
     @Bean
     public InternalResourceViewResolver configureInternalResourceViewResolver() {
         InternalResourceViewResolver resolver = new InternalResourceViewResolver();
         resolver.setPrefix("/WEB-INF/views/");
         resolver.setSuffix(".jsp");
         return resolver;
     }
}

这是测试类:

package com.myapp.test.integration;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;

import com.myapp.config.WebConfig;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes={ WebConfig.class})
@WebAppConfiguration
public class HomeControllerTest {

    @Test
    public void testController(){
        System.out.println("Executing test");
    }   

}

当我尝试运行测试时，我得到以下信息(我已启用调试以获取更多信息):

您忘记设置 Activity 配置文件。这是一个正在运行的示例测试。家庭 Controller :

package com.myapp.test.integration;

import org.springframework.context.annotation.Profile;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 *
 */
@Controller
@Profile("cloudx")
public class HomeController {
    @RequestMapping("/test")
    public String test() {
        return "test";
    }
}

网络配置:

package com.myapp.test;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

@Configuration
@EnableWebMvc
@ComponentScan("com.myapp.test")
public class WebConfig {
    @Bean
    public InternalResourceViewResolver configureInternalResourceViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/views/");
        resolver.setSuffix(".jsp");
        return resolver;
    }
}

家庭 Controller 测试:

package com.myapp.test;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ActiveProfiles;
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.MvcResult;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = WebConfig.class)
@WebAppConfiguration
@ActiveProfiles("cloudx")
public class HomeControllerTest {
    @Autowired
    protected WebApplicationContext wac;
    protected MockMvc mockMvc;

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

    @Test
    public void test() throws Exception {
        MvcResult result = mockMvc.perform(get("/test")).andExpect(status().isOk()).andReturn();
        System.out.println(result.getResponse().getContentAsString());
    }

}
