关于 Spring Boot 项目，我添加了 "validation-api" 但 Postman 没有抛出错误，它允许存储空白字段（@NotBlank 不起作用）。然后我使用了以下内容 -

  1. <dependency>
  2.     <groupId>org.springframework.boot</groupId>
  3.     <artifactId>spring-boot-starter-validation</artifactId>
  4.     <version>2.4.1</version>
  5. </dependency>

它起效了。

英文:

For Spring Boot project, I added "validation-api" but postman was not throwing error and it allowed to store Blank fields (@NotBlank was not working).
Then I used this -

  1. &lt;dependency&gt;
  2. &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
  3. &lt;artifactId&gt;spring-boot-starter-validation&lt;/artifactId&gt;
  4. &lt;version&gt;2.4.1&lt;/version&gt;
  5. &lt;/dependency&gt;

and it worked.

需要添加validation-api依赖

  1. <dependency>
  2. <groupId>javax.validation</groupId>
  3. <artifactId>validation-api</artifactId>
  4. <version>2.0.1.Final</version>
  5. </dependency>
英文:

You need to add validation-api dependency

  1. &lt;dependency&gt;
  2. &lt;groupId&gt;javax.validation&lt;/groupId&gt;
  3. &lt;artifactId&gt;validation-api&lt;/artifactId&gt;
  4. &lt;version&gt;2.0.1.Final&lt;/version&gt;
  5. &lt;/dependency&gt;

答案3

得分: 1

你只需要添加这个依赖：

  1. <dependency> 
  2. <groupId>org.springframework.boot</groupId> 
  3. <artifactId>spring-boot-starter-validation</artifactId> 
  4. </dependency>
英文:

you just need to add this dependency:

&lt;dependency&gt;
&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
&lt;artifactId&gt;spring-boot-starter-validation&lt;/artifactId&gt;
&lt;/dependency&gt;
