Question

我正在使用spring boot 1.5.4.RELEASE

验证请求的内容

@RequestMapping(method = PATCH, value = "/{uniqueId}", produces = APPLICATION_JSON_VALUE)
public ResponseEntity<UserResource> setGlobalRoles(@PathVariable("uniqueId") String uniqueId,
        @Valid @RequestBody UserPatch patch) { ... }

该课程如下：

public class UserPatch {
  @Valid
  private List<@GlobalRoleExists String> globalRoles = new ArrayList<>();

  ...

  public List<String> getGlobalRoles() {
    return globalRoles;
  }

  public void setGlobalRoles(List<String> globalRoles) {
    this.globalRoles = globalRoles;
  }

如果列表中的某个元素对约束无效，则会引发以下错误。

org.springframework.beans.NotReadablePropertyException: Invalid property 'globalRoles[1].<collection element>' of bean class [com.app.UserPatch]: Bean property 'globalRoles[1].<collection element>' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?

我注意到路径“globalRoles [1]。＆＃39;由hibernate（org.hibernate.validator.internal.engine.path.NodeImpl）生成，但我不知道我是否遗漏了某些东西，或者是否有可能无法做到这一点。

从Spring Boot 1.4.x升级到1.5.6时遇到了同样的问题。

问题记录在Spring issue tracker，是由于在验证失败时Hibernate 5.3.x中生成的字符串发生了变化。

Spring Framework 4.3.11应该包含该修复，同时您可以明确指定对Hibernate版本5.2.5的依赖（如果您正在使用Gradle，则为compile group: 'org.hibernate', name: 'hibernate-validator', version: '5.2.5.Final'。）

NotReadablePropertyException：无效的属性＆＃39; <collection element =“”>＆＃39;验证字符串
