本篇内容主要讲解“spring oauth2 +springboot sso的案例分析”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“spring oauth2 +springboot sso的案例分析”吧!

一、依赖

        <dependency>
            <groupId>org.springframework.security.oauth.boot</groupId>
            <artifactId>spring-security-oauth3-autoconfigure</artifactId>
            <version>2.1.6.RELEASE</version>
        </dependency>

二、服务端

1.服务端需要的是授权与身份验证，通过配置@EnableAuthorizationServer、@EnableWebSecurity、@EnableResourceServer来完成配置。

2.先来配置WebSecurity的配置

package com.example.oauth;

import org.springframework.boot.autoconfigure.security.SecurityProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.annotation.Order;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.BeanIds;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.builders.WebSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.provisioning.InMemoryUserDetailsManager;

/**
 * @author sorata
 * @date 2019-07-23 09:19
 */
@Configuration
@EnableWebSecurity
@Order(SecurityProperties.BASIC_AUTH_ORDER)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {


    @Bean
    public UserDetailsService myUserDetailsService(){
        return new InMemoryUserDetailsManager(User.builder().username("admin").password(passwordEncoder().encode("admin")).roles("ADMIN").build());
    }

    @Bean
    public BCryptPasswordEncoder passwordEncoder(){
        return new BCryptPasswordEncoder();
    }


    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(myUserDetailsService()).passwordEncoder(passwordEncoder());
    }

    @Bean(BeanIds.AUTHENTICATION_MANAGER)
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        super.configure(web);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable().antMatcher("/**")
                .authorizeRequests()
                .antMatchers("/","/login","/oauth/**").permitAll()
                .anyRequest().authenticated()
                .and().httpBasic().and().formLogin()
                .and().logout();
    }
}

note：首先是配置用户UserDetailsService，然后配置密码策略。主要的部分是 configure(HttpSecurity http) 方法，这里当我在formLogin()后配置了验证完成转发，即successForwardUrl(“/main”)后，sso客户端请求验证完成时，不会跳转到客户端的请求地址，而是跳转到验证成功的服务端地址 /main。

3.编写一个用户信息的controller

package com.example.oauth;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.security.Principal;

/**
 * @author sorata
 * @date 2019-07-23 09:17
 */
@RestController
public class UserController {

    @RequestMapping("/user")
    public Principal principal(Principal principal){
        return principal;
    }

    @RequestMapping("/user2")
    public Principal principal2(Principal principal){
        return principal;
    }

}

note：作用就是测试和之后客户端填写的服务器用户信息的url

4.资源服务器

package com.example.oauth;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.oauth3.config.annotation.web.configuration.EnableResourceServer;
import org.springframework.security.oauth3.config.annotation.web.configuration.ResourceServerConfigurerAdapter;

/**
 * @author sorata
 * @date 2019-07-23 09:50
 */
@Configuration
@EnableResourceServer
public class ResourceConfig extends ResourceServerConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.csrf().disable().antMatcher("/user")
                .authorizeRequests().anyRequest().authenticated();
    }
}

6. 重要的认证服务端

package com.example.oauth;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.oauth3.config.annotation.configurers.ClientDetailsServiceConfigurer;
import org.springframework.security.oauth3.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;
import org.springframework.security.oauth3.config.annotation.web.configuration.EnableAuthorizationServer;
import org.springframework.security.oauth3.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;
import org.springframework.security.oauth3.config.annotation.web.configurers.AuthorizationServerSecurityConfigurer;
import org.springframework.security.oauth3.provider.token.TokenStore;
import org.springframework.security.oauth3.provider.token.store.InMemoryTokenStore;

/**
 * @author sorata
 * @date 2019-07-23 10:06
 */
@Configuration
@EnableAuthorizationServer
public class SsoServerConfig extends AuthorizationServerConfigurerAdapter {

    @Autowired private AuthenticationManager authenticationManager;
    @Autowired private BCryptPasswordEncoder passwordEncoder;
    /**
     * 如果出现错误 在主类上去掉默认配置
     * {@link SsoServerApplication}
     */
    @Autowired private UserDetailsService detailsService;

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security.allowFormAuthenticationForClients()
                .tokenKeyAccess("permitAll()")
                .checkTokenAccess("isAuthenticated()")
                .passwordEncoder(passwordEncoder);
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory().withClient("cocos")
                .secret(passwordEncoder.encode("cocos"))
                .autoApprove(true)
                .redirectUris("http://localhost:9090/client/login")
                .scopes("all")
                .authorities("ADMIN")
                .authorizedGrantTypes("authorization_code","password","refresh_token")
                .accessTokenValiditySeconds(10000)
                .refreshTokenValiditySeconds(10000);
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.authenticationManager(authenticationManager)
                .userDetailsService(detailsService).tokenStore(tokenStore());
    }


    @Bean
    public TokenStore tokenStore(){
        return new InMemoryTokenStore();
    }
}

三、客户端

1.客户端实现比较简单，如果想针对行的修改，自定义那么可以根据后面参考地址研读。

2.application.properties

security.oauth3.client.authentication-scheme=form
security.oauth3.client.user-authorization-uri=http://localhost:8080/server/oauth/authorize
security.oauth3.client.access-token-uri=http://localhost:8080/server/oauth/token
security.oauth3.client.client-id=cocos
security.oauth3.client.client-secret=cocos
security.oauth3.resource.user-info-uri=http://localhost:8080/server/user


server.servlet.context-path=/client

server.port=9090

3.主类添加注解

package com.example.oauth;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.security.oauth3.client.EnableOAuth3Sso;

@SpringBootApplication
@EnableOAuth3Sso
public class SsoClientApplication {

    public static void main(String[] args) {
        SpringApplication.run(SsoClientApplication.class, args);
    }

}

4.用户的接口

package com.example.oauth;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.security.Principal;

/**
 * @author sorata
 * @date 2019-07-23 10:30
 */
@RestController
public class UserController {


    @RequestMapping("/user")
    public Principal principal(Principal principal){
        return principal;
    }

}
