spring boot MockMVC的使用demo

使用MockMVC进行带有参数的post访问

package com.springboot.demo;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockHttpServletRequestBuilder;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;

@RunWith(SpringRunner.class)
@SpringBootTest
public class HelloWorldTest {

    private MockMvc mockMvc;
　　//启用web上下文
    @Autowired
    private WebApplicationContext context;
　　//使用上下文构建mockMvc
    @Before
    public void setUp(){
        mockMvc = MockMvcBuilders.webAppContextSetup(context).build();
    }
　　//存在controller，其访问路径为/hello,且带有一个参数name
    @Test
    public void getHello() throws Exception {
        mockMvc.perform(MockMvcRequestBuilders.post("/hello?name=zhangsan")
                .accept(MediaType.APPLICATION_JSON_UTF8)).andDo(print());
    }
}

运行该单元测试，其运行结果为

MockHttpServletRequest:
      HTTP Method = POST
      Request URI = /hello
       Parameters = {name=[zhangsan]}
          Headers = {Accept=[application/json;charset=UTF-8]}
             Body = <no character encoding set>
    Session Attrs = {}

Handler:
             Type = null

Async:
    Async started = false
     Async result = null

Resolved Exception:
             Type = org.springframework.web.HttpRequestMethodNotSupportedException

ModelAndView:
        View name = null
             View = null
            Model = null

FlashMap:
       Attributes = null

MockHttpServletResponse:
           Status = 405
    Error message = Request method 'POST' not supported
          Headers = {Allow=[GET]}
     Content type = null
             Body = 
    Forwarded URL = null
   Redirected URL = null
          Cookies = []

　　从上面我们可以看到访问方式，访问路径，参数，访问头，ModelAndView
