import static org.springframework.test.web.servlet.setup.MockMvcBuilders.*;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;注入需要的组件：
代码语言：javascript复制@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(locations = {
"classpath:spring/applicationContext.xml",
"classpath:spring/spring-mvc-servlet.xml"
})
public class SpringMVCTest {
@Autowired
private WebApplicationContext wac;
protected MockMvc mockMvc;
@Before
public void setup() {
this.mockMvc = webAppContextSetup(this.wac).build();
}
@Test
public void empty() {
}
}编写单元测试，这个例子是提交一个整体的字符串
代码语言：javascript复制@Test
public void testPostBody() throws Exception {
String jsonString = JsonObjectUtils.beanToJson(ImmutableMap.of("username", "me", "password", "123456",
"timestamp", System.currentTimeMillis()));
ResultActions resultActions = mockMvc.perform(
(post("/api/login.do")
.contentType(org.springframework.http.MediaType.APPLICATION_JSON)
.content(jsonString).characterEncoding("utf-8")))
.andExpect(status().isOk()).andDo(print());
String contentAsString = resultActions.andReturn().getResponse().getContentAsString();
System.out.println(contentAsString);
}
