Spring 4集成Junit4
前言
springmvc4 整合 junit4，测试service层和controller层。
环境
- Spring-4.2.5.RELEASE
- Junit-4.11

测试service
./src/main/java目录下service代码如下：
package com.sicimike.service;
import org.springframework.stereotype.Service;
@Service
public class ExampleService {
public void show() {
System.out.println("ExampleService.show()");
}
}
./src/test/java目录下对应的test类代码如下：
@Test标注的方法(testShow)必须满足：public修饰、返回类型void、没有参数
package com.sicimike.service;
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;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:applicationContext.xml" })
public class ExampleServiceTests {
@Autowired
private ExampleService exampleService;
@Test
public void testShow() {
exampleService.show();
}
}
测试controller
./src/main/java目录下controller代码如下：
package com.sicimike.web;
import java.util.HashMap;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.sicimike.service.ExampleService;
@Controller
public class ExampleController {
@Autowired
private ExampleService exampleService;
@ResponseBody
@RequestMapping("/show")
public Map show(String id) {
System.out.println("id is " + id);
exampleService.show();
Map map = new HashMap();
map.put("code", "200");
map.put("message", "success");
return map;
}
}
请求url：GET http://localhost:8080/show?id=123
返回数据：
{
"code": "200",
"message": "success"
}
./src/test/java目录下对应的test类代码如下：
@Test标注的方法(testShow)必须满足：public修饰、返回类型void、没有参数
package com.sicimike.web;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.MediaType;
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.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;
@WebAppConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:applicationContext.xml" })
public class ExampleControllerTests {
private MockMvc mockMvc;
@Autowired
WebApplicationContext webApplicationContext;
@Before
public void setUp(){
mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
}
@Test
public void testShow() throws Exception {
String url = "/show?id=123";
MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.get(url)
.accept(MediaType.APPLICATION_JSON))
.andExpect(MockMvcResultMatchers.status().isOk())
.andReturn();
System.out.println(mvcResult.getResponse().getContentAsString());
}
}
