java.lang.IllegalArgumentException：无法解析值"${crossOrigin}"中的占位符"crossOrigin"

Question

我正在为控制器类编写测试用例。当我在像这样的每个方法之上添加跨源时@CrossOrigin(origins = "http://localhost:4200")那时测试用例正常运行，没有错误。

但我不想在每个方法之上硬编码跨源。为此，我在application.property文件中添加一个变量，并在类顶部的控制器中访问该变量。当我像这样添加跨源时，我能够从其他机器访问我的服务。但是我的测试用例失败了。

当我评论时，来自控制器类测试用例的这个@CrossOrigin(origins = "${crossOrigin}")运行正常。

谁能告诉我为什么会这样？

帐户控制器.java

package com.spacestudy.controller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PutMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.querydsl.core.Tuple;
import com.spacestudy.model.Account;
import com.spacestudy.model.*;
import com.spacestudy.services.*;
@RestController
@CrossOrigin(origins = "${crossOrigin}")
@RequestMapping("/api.spacestudy.com/spacestudy/rockefeller/admin/account")
public class AccountController {
@Autowired
AccountService accService;  

@GetMapping("/loadAcctLocationList")
public ResponseEntity<List<Account>> findLocation() {
return  ResponseEntity.ok(accService.findLocation());
}

应用程序属性

crossOrigin=http://localhost:4200
server.port=8088
spring.datasource.url=jdbc:postgresql://localhost/TestDB_002
spring.datasource.username=postgres
spring.datasource.password=postgres

测试帐户控制器

@RunWith(SpringRunner.class)
public class TestAccountController {
private MockMvc mockMvc;
@Mock
private AccountService accountService;
@InjectMocks
private AccountController accountController;
@Before
public void setup() {
mockMvc = MockMvcBuilders.standaloneSetup(accountController).build();
}
@Test
public void findLocationTest() throws Exception {
Account account = new Account();
account.setsLocation("US");
account.setsLocation("pune");
List<Account> accountObj = new ArrayList<Account>();
accountObj.add(account);
Mockito.when(accountService.findLocation()).thenReturn(accountObj);
mockMvc.perform(get("/api.spacestudy.com/spacestudy/rockefeller/admin/account/loadAcctLocationList"))
.andExpect(status().isOk()).andExpect(jsonPath("$[0].sLocation", is("pune")));
}

Answer 1

我意识到这个问题已经有一年多了，但是我也遇到了这个问题。

解决方案是需要为 MockMvc 提供占位符值。

所以以下内容：

mockMvc = MockMvcBuilders.standaloneSetup(accountController).build();

应该是 ：

mockMvc = MockMvcBuilders.standaloneSetup(accountController).addPlaceholderValue("crossOrigin","https://some.url.com").build();
