Validation annotations NOT working at all (Tried all suggested solutions)-CodePudding

I am trying to use the @Valid and @NotBlank annotations in my spring boot project within IntelliJ IDEA 2022.2.3 (Community Edition) Build #IC-222.4345.14, built on October 5, 2022

I have added dependency like below in my project pom.xml

<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-validation</artifactId>
    <scope>test</scope>
</dependency>

In my entity class i have added @NotBlank annotation as below

@NotBlank(message = "Please add the department name")
private String departmentName;

In my controller class i have added @Valid annotation as well

@PostMapping("/departments")
public Department saveDepartment(@Valid @RequestBody Department department)
{
    return departmentService.saveDepartment(department);
}

Even with all this i don't think the validation APIs are working.

My spring boot version is

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.7.5</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

Ideally i should be getting validation error if i don't pass the department name in my POST request BUT i never get any error with blank department name where my annotations are present.

I have tried various suggested solutions like closing and restarting IntelliJ Idea, Rebuilt the project. Also, I have tried invalidating the cache. NOTHING IS WORKING !!! The dependencies also seem to be all GOOD.

What else I could try?

CodePudding user response：

Remove the scope test from the spring-boot-starter-validation dependency, you need this dependency during runtime as well.

Create a unit/integration-test that can test your validation. Run the test using a Maven command like mvn clean test. If this succeeds and the same test fails when executed within IntelliJ, you have an IDE issue.

I had to update my IntelliJ IDEA Community to latest available version which is below and everything worked good after this
