Junit4测试Controller层

这类比较常用的测试类我们就直接做一个Base封装好，可以在测试的时候更好的看核心部分

package com.alumni_circle.core.junit;

import com.alumni_circle.JunitTest;
import org.apache.log4j.Logger;
import org.junit.Before;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.mock.web.MockHttpServletRequest;
import org.springframework.mock.web.MockHttpServletResponse;
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;

/**

 * @since 2020-07-08 21:10
 */
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration(value = "src/main/webapp")
@ContextConfiguration(locations={
    
    "classpath:mybatis-config.xml","classpath:mvc-dispatcher.xml","classpath:applicationContext.xml"})
@ComponentScan(basePackages={
    
    "com.alumni_circle.controller", "com.alumni_circle.service"})
public class BaseJunit {
    
    
    private static final Logger log = Logger.getLogger(JunitTest.class);

    @Autowired
    WebApplicationContext webApplicationContext;

    protected MockMvc mockMvc;

    protected MockHttpServletRequest request;
    protected MockHttpServletResponse response;

    /**
     * 初始化SpringmvcController类测试环境
     */
    @Before
    public void setup(){
    
    
        //加载web容器上下文
        mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }
}

然后用其子类继承BaseJunit

package com.alumni_circle;

import com.alumni_circle.core.junit.BaseJunit;
import org.junit.Test;
import org.springframework.http.MediaType;

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

/**

 * @since 2020-07-08 01:29
 */
public class JunitTest extends BaseJunit {
    
    


    //post请求需要的对象参数
    String str = "{}";
    @Test
    public void testTest() throws Exception{
    
    
        String responseString = mockMvc.perform
                (
                        //请求的url,请求的方法是get
//                        get("/ac/selectByPageNumSize")
                        //数据的格式
//                        .contentType(MediaType.APPLICATION_JSON)
//                      //添加参数(可以添加多个)
//                      .param("id","1")

                        //请求的url,请求方法是POST
                        post("/gossip/select")
                        .contentType(MediaType.APPLICATION_JSON).content(str)
                )
                //返回的状态是200
                .andExpect(status().isOk())
                //打印出请求和相应的内容
                .andDo(print())
                //将相应的数据转换为字符串
                .andReturn().getResponse()
                .getContentAsString();
        System.out.println("对象" + responseString);
    }
}
