实现一个最基本的OAuth3认证

项目使用3个独立的工程分别实现认证服务、资源服务器和单点登陆服务器



源码地址

添加项目依赖

allprojects {
    apply plugin: 'idea'
    apply plugin: 'java'
}
buildscript {
    ext {
        springBootVersion = '2.0.0.RELEASE'
    }
    repositories {
        maven { url 'http://maven.aliyun.com/mvn/repository/' }
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

subprojects {
    apply plugin: 'java'
    apply plugin: 'org.springframework.boot'
    apply plugin: 'io.spring.dependency-management'
    repositories {
        maven { url 'http://maven.aliyun.com/mvn/repository/' }
        mavenCentral()
    }
}
project("sso-auth-server") {
    dependencies {
        compile 'org.springframework.boot:spring-boot-starter-web'
        compile 'org.springframework.boot:spring-boot-starter-security'
        compile 'org.springframework.security.oauth.boot:spring-security-oauth2-autoconfigure:2.0.0.RELEASE'
    }
}


project("sso-auth-client") {
    dependencies {
        compile 'org.springframework.boot:spring-boot-starter-web'
        compile 'org.springframework.boot:spring-boot-starter-security'
        compile 'org.springframework.security.oauth.boot:spring-security-oauth2-autoconfigure:2.0.0.RELEASE'
    }
}

project("sso-auth-resource") {
    dependencies {
        compile 'org.springframework.boot:spring-boot-starter-web'
        compile 'org.springframework.boot:spring-boot-starter-security'
        compile 'org.springframework.security.oauth.boot:spring-security-oauth2-autoconfigure:2.0.0.RELEASE'
    }
}

认证服务器配置

• 使用EnableAuthorizationServer注解开启认证服务

@SpringBootApplication
@EnableAuthorizationServer
public class AuthenticationApplication {
   

    public static void main(String[] args) {
   
        new SpringApplicationBuilder(AuthenticationApplication.class)
                .run(args);
    }

}

• 使用EnableWebSecurity注解开启权限验证，并做相关配置

@EnableWebSecurity
public class
