Spring 响应中未显示引导验证错误消息

Question

我有以下简单项目来测试 spring 引导验证。我正在使用 Spring 引导版本 2.5.6

pom.xml

中的验证依赖项

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-validation</artifactId>
</dependency>

DTO 对象

import javax.validation.constraints.NotNull;

public class DepartmentDTO {

    @NotNull(message = "Department name can not be empty")
    private String name;

    // getter and setter
}

REST 控制器

@RestController
public class DepartmentResource {

    @PostMapping("/departments")
    public ResponseEntity<DepartmentDTO> createDepartment(@Valid @RequestBody DepartmentDTO department) {
        return new ResponseEntity<>(department, HttpStatus.OK);
    }
}

当我使用 空名称 发出请求时，我收到了错误响应，但消息丢失了：

{
    "timestamp": "2021-12-03T09:13:52.729+00:00",
    "status": 400,
    "error": "Bad Request",
    "path": "/departments"
}

Answer 1

Spring 引导限制错误响应中包含的信息，以降低将有关应用程序的敏感信息泄露给客户端的风险。您可以通过在 application.properties 或 application.yml.

中设置 some properties 来显式启用响应中的附加信息

server.error.include-binding-errors=always
server.error.include-message=always
