Junit Mockito如何将用户对象传递给测试方法

Question

我们有一个 Spring Rest 控制器，它接受一个带有（Authenticated 注释）和几个其他参数的 User 对象。你能告诉我们如何在 JUnit 测试方法中传递这个用户对象吗？我们试图在测试方法中如下调用，但低于异常堆栈跟踪。

测试调用：

mockMvc.perform(get("/test1/test2/test3/test4")
    .with(SecurityMockMvcRequestPostProcessors.user(new UsrHelpr().create()))
    .accept(MediaType.APPLICATION_JSON)
    .param("name", "testting"))
    .andExpect(status().isOk()).andReturn();

堆栈跟踪：

在您的情况下，只需将用户对象作为参数值传递给模拟 mvc 请求，如下所示：

package com.example.stackoverflowsecurityissue;

import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
public class TestController {

    @RequestMapping(value = "/request", method = RequestMethod.GET)
    public ResponseEntity getMyRequests(MyUser user, @RequestParam(value = "status", required = true) String status) throws Exception {
        System.out.println(" user recevied " + user.toString());
        return ResponseEntity.ok().build();


    }

    protected static class MyUser {

        private String userName;

        private String password;

        public String getUserName() {
            return userName;
        }

        public void setUserName(String userName) {
            this.userName = userName;
        }

        public String getPassword() {
            return password;
        }

        public void setPassword(String password) {
            this.password = password;
        }

        public MyUser(String userName) {
            this.userName = userName;
        }

        public MyUser(String userName, String password) {
            this.userName = userName;
            this.password = password;
        }

        @Override
        public String toString() {
            return "MyUser{" +
                    "userName='" + userName + '\'' +
                    ", password='" + password + '\'' +
                    '}';
        }

        public MyUser() {
        }

    }
}

我的控制器测试：

package com.example.stackoverflowsecurityissue;

import com.fasterxml.jackson.databind.ObjectMapper;
import org.junit.Test;
import org.junit.runner.RunWith;
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.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.MockMvcBuilder;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;
import static org.springframework.test.web.servlet.setup.MockMvcBuilders.*;

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class StackoverflowSecurityIssueApplicationTests {

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void performGetReq() throws Exception {
        ObjectMapper mapper=new ObjectMapper();
        mockMvc.perform(get("/request").
                param("userName","hello").param("password","hello").param("status","hello")).andExpect(status().isOk());
    }

}

输出：

 user recevied MyUser{userName='hello', password='hello'}
