Steps to Implement 403 Error in Spring Boot Post Request
Below are the steps to create and solve 403 Error in Spring Boot Post Request.
Step 1:
First, create a basic Spring Boot Stater project by using Spring initializr with required project dependencies, Below are the required dependencies to Solve 403 Error in Spring Boot Post Request.
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-security'
implementation 'org.springframework.boot:spring-boot-starter-web'
compileOnly 'org.projectlombok:lombok'
developmentOnly 'org.springframework.boot:spring-boot-devtools'
annotationProcessor 'org.projectlombok:lombok'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
testImplementation 'org.springframework.security:spring-security-test'
}
main class method:
package com.app;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringApplicationsApplication {
public static void main(String[] args) {
SpringApplication.run(SpringApplicationsApplication.class, args);
}
}
Step 2:
- Now, we created one java class in the main package of the project.
- And In that class, we define one PostMapping method for creating API end point by using @PostMapping Spring Annotation.
- And also created one method i.e. postExample() and this method take a string as input by using @RequestBody Spring Annotation.
package com.app;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class MyController {
// Endpoint to handle POST requests to "/api/example"
@PostMapping("/api/example")
public String postExample(@RequestBody String data) {
// Return a response with received data
return "Received data: " + data;
}
}
Step 3:
- Now, we created one more java class in main package.
- This is used for security configuration purpose means it can handle all requests types and this configuration class provides access to the different clients like user, admin and other.
- This configuration class is created by using @Configuration and @EnableWebSecurity Spring Annotations.
package com.app;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpMethod;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
// Configure HTTP security
http
.authorizeRequests()
// Allow only users with role ADMIN to access POST requests to "/api/example"
.antMatchers(HttpMethod.POST, "/api/example").hasRole("ADMIN")
// Allow all other requests to be accessed by anyone
.anyRequest().permitAll()
.and()
// Configure form-based authentication
.formLogin()
.and()
// Configure HTTP Basic authentication
.httpBasic();
}
}
Step 4:
- Once required logic is developed, then run this project as Spring Boot Application.
- After this, hit the required APIs and this application will be running on 8080 port by using Apache Tomcat server.
Step 5:
After running the project, open the Post Man tool and hit the API. Then we will get the below output.
http://localhost:8080/api/example
Output: 403 Forbidden Error
How to Solve 403 Error in Spring Boot Post Request?
Spring Boot is one of the frameworks used in developing web applications, and it provides a lot of features to solve real-time problems in software industries. In this article, we will explain how to solve the 403 error in the Spring Boot post request. This error is raised due to security configuration, authentication and authorization, and other aspects. This means when we hit related API, then the request goes to the server from the client and the request is processed by the server. The server can handle the requests if proper permissions are not granted to that request, and the request can’t access the resources.
