Sa-token integration code example display in springboot

sa-tokenis a lightweight Java permission authentication framework that can be easily integrated into Spring Boot projects to provide concise authentication and authorization functions. Althoughsa-tokenIt does not directly support the integration of OAuth 2.0, but you can combine the authentication process of OAuth 2.0 withsa-tokenThe permission control is used in combination.

Here is a simple example showing how tosa-tokenIntegrated into Spring Boot project:

Add tosa-tokenRely on yoursIn the file:

&lt;dependency&gt;
&lt;groupId&gt;cn.dev33&lt;/groupId&gt;
&lt;artifactId&gt;sa-token-spring-boot-starter&lt;/artifactId&gt;
&lt;version&gt;Latest version&lt;/version&gt;
&lt;/dependency&gt;

Make sure you are using the latestsa-tokenVersion.

# Examplesa-token:

Create a configuration class to initializesa-token：

import cn.;
import cn.;
import cn.;
import cn.;
import ;
import ;
import ;
import ;
@Configuration
@AutoConfigureAfter()
public class SaTokenConfig {
@Bean
@ConditionalOnMissingBean
public SaTokenFilter saTokenFilter(SaTokenProperties saTokenProperties) {
return new SaTokenFilter(saTokenProperties);
}
// You can add custom SaToken initialization code here// For example: Set global permission verification rules, login verification processing, etc.@Bean
public void initSaToken() {
// Initialize Sa-Token and set global permission verification rules((request, response, exception) -&gt; {
// Here you can customize the global permission verification logic// For example: Return custom unauthorized prompt information("application/json;charset=UTF-8");
().write("{\"code\":401,\"msg\":\"Unauthorized\"}");
().flush();
().close();
});
}
}

Use in your Controllersa-tokenThe annotations provided for permission control:

import cn.;
import cn.;
import ;
import ;
@RestController
public class MyController {
@GetMapping("/needPermission")
@SaCheckPermission("permission1") // Here we will verify whether the user has permission1 permissionpublic String needPermission() {
return "you have permission1";
}
@GetMapping("/needRole")
@SaCheckRole("admin") // Here we will verify whether the user has the admin rolepublic String needRole() {
return "you are admin";
}
}
