SpringBoot对Controller进行单元测试的实现代码 附乱码解决方案

controller代码

package com.keafmd.controller;

import org.springframework.web.bind.annotation.requestmapping;
import org.springframework.web.bind.annotation.restcontroller;

import java.util.hashmap;
import java.util.map;

/**
 * keafmd
 *
 * @classname: hellocontroller
 * @description:
 * @author: 牛哄哄的柯南
 * @date: 2021-04-02 9:42
 * @blog: https://keafmd.blog.csdn.net/
 */
@restcontroller
public class hellocontroller {

 @requestmapping("/hello")
 map hello(){
  map map = new hashmap();
  map.put("keafmd","牛哄哄的柯南");
  map.put("success",true);
  return map;

 }
}

单元测试代码

package com.keafmd;

import com.keafmd.springboot02application;
import com.keafmd.controller.hellocontroller;
import org.junit.jupiter.api.beforeeach;
import org.junit.jupiter.api.test;
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.context.contextconfiguration;
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.mockmvcresulthandlers;
import org.springframework.test.web.servlet.result.mockmvcresultmatchers;
import org.springframework.test.web.servlet.setup.mockmvcbuilders;
import org.springframework.web.context.webapplicationcontext;

/**
 * keafmd
 *
 * @classname: mvctest
 * @description:
 * @author: 牛哄哄的柯南
 * @date: 2021-04-02 10:59
 * @blog: https://keafmd.blog.csdn.net/
 */
@springboottest(classes = springboot02application.class)
@autoconfiguremockmvc //相当于是使用 context 上下文构造一个 mvc对象
public class mvctest {

 //模拟访问 controller
 @autowired
 mockmvc mvc;

 @test
 public void test() throws exception {
  mvcresult result = mvc.perform(
    mockmvcrequestbuilders.get("/hello").
      accept(mediatype.application_json)).
    andexpect(mockmvcresultmatchers.status().isok()).
    anddo(mockmvcresulthandlers.print()).andreturn();

 }
}

测试结果

乱码解决

把注解替换为：↓
@requestmapping(value = "/hello",produces = {"application/json;charset=utf-8"})

hellocontroller：

package com.keafmd.controller;

import org.springframework.web.bind.annotation.getmapping;
import org.springframework.web.bind.annotation.postmapping;
import org.springframework.web.bind.annotation.requestmapping;
import org.springframework.web.bind.annotation.restcontroller;

import java.util.hashmap;
import java.util.map;

/**
 * keafmd
 *
 * @classname: hellocontroller
 * @description:
 * @author: 牛哄哄的柯南
 * @date: 2021-04-02 9:42
 * @blog: https://keafmd.blog.csdn.net/
 */
@restcontroller
public class hellocontroller {

 @requestmapping(value = "/hello",produces = {"application/json;charset=utf-8"})
 //@requestmapping("/hello")
 map hello(){
  map map = new hashmap();
  map.put("keafmd","牛哄哄的柯南");
  map.put("success",true);
  return map;

 }
}
