spring boot junit controller

MockMvc 來自Spring Test，它允許您通過一組方便的builder類向 DispatcherServlet 發送HTTP請求，並對結果作出斷言。請注意，@AutoConfigureMockMvc 與@SpringBootTest 需要一起注入一個MockMvc 實例。在使用@SpringBootTest 時候，我們需要創建整個應用程序上下文。

 

示例代碼:

import org.junit.Test;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.test.annotation.Rollback;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
import org.springframework.transaction.annotation.Transactional;

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;

@RunWith(SpringRunner.class)//表示使用Spring Test組件進行單元測試
@Transactional//回滾所有增刪改
@SpringBootTest
@AutoConfigureMockMvc//注入一個MockMvc實例
public class DingControllerTest {

    private final static Logger logger = LoggerFactory.getLogger(DingControllerTest.class);

    @Autowired
    private MockMvc mockMvc;

    @Test
    @Rollback(false)//取消回滾public void getSignature() throws Exception {
        String responseString = mockMvc.perform(
                post("/ding/getSignature")//請求的url,請求的方法是post
                        .contentType(MediaType.APPLICATION_JSON)//數據的格式
                        .param("url", "https://www.baidu.com/")//添加參數
        ).andExpect(status().isOk())//返回的狀態是200
                .andExpect(MockMvcResultMatchers.jsonPath("$.state").value(1)) //判斷某返回值是否符合預期
                .andDo(print())//打印出請求和相應的內容
                .andReturn().getResponse().getContentAsString();//將相應的數據轉換為字符串
        logger.info("post方法/ding/getSignature,{}", responseString);
    }

}
