Spring Boot集成Spring Cloud Security进行安全增强

大家好，我是微赚淘客返利系统3.0的小编，是个冬天不穿秋裤，天冷也要风度的程序猿！

在微服务架构中，服务的安全性是至关重要的。Spring Cloud Security提供了一套安全工具集，帮助开发者快速实现认证和授权。本文将介绍如何在Spring Boot应用中集成Spring Cloud Security来增强安全性。

一、Spring Cloud Security简介

Spring Cloud Security是Spring Security的扩展，它提供了对Spring Cloud体系中的服务认证和授权的支持，包括OAuth2、JWT等。

二、添加依赖

在Spring Boot项目的pom.xml中添加Spring Cloud Security的依赖：

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-oauth2</artifactId>
</dependency>

确保项目中已经包含了Spring Cloud的依赖管理。

三、配置Security

在application.properties或application.yml中配置Security：

security.oauth2.resource.id=juwatech-service
security.oauth2.resource.user-info-uri=http://localhost:9999/userinfo
security.oauth2.client.client-id=your-client-id
security.oauth2.client.client-secret=your-client-secret

四、启用Security

在Spring Boot应用中启用Spring Cloud Security：

package cn.juwatech.config;

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;

@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/api/public/**").permitAll()
                .anyRequest().authenticated()
            .and()
                .oauth2ResourceServer()
                    .jwt();
    }
}

五、使用JWT进行令牌认证

  1. 配置JWT的解析和验证：
package cn.juwatech.config;

import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.oauth2.server.resource.authentication.JwtAuthenticationConverter;
import org.springframework.security.oauth2.server.resource.authentication.JwtGrantedAuthoritiesConverter;

@EnableWebSecurity
public class JwtSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        JwtAuthenticationConverter jwtAuthenticationConverter = new JwtAuthenticationConverter();
        jwtAuthenticationConverter.setJwtGrantedAuthoritiesConverter(new JwtGrantedAuthoritiesConverter());

        http
            .oauth2Login()
                .and()
                .oauth2ResourceServer()
                    .jwt()
                    .jwtAuthenticationConverter(jwtAuthenticationConverter);
    }
}
  1. 使用@PreAuthorize或@Secured注解进行方法级别的安全控制：
package cn.juwatech.controller;

import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class SecuredController {

    @GetMapping("/secure-data")
    @PreAuthorize("hasAuthority('SCOPE_READ')")
    public String secureData() {
        return "Secure data";
    }
}

六、集成OAuth2.0认证服务器

  1. 添加OAuth2.0认证服务器依赖：
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-oauth2-resource-server</artifactId>
</dependency>
  1. 配置OAuth2.0认证服务器：
package cn.juwatech.config;

import org.springframework.context.annotation.Bean;
import org.springframework.security.oauth2.provider.token.DefaultAccessTokenConverter;
import org.springframework.security.oauth2.provider.token.TokenStore;
import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;
import org.springframework.security.oauth2.provider.token.store.JwtTokenStore;

@Configuration
public class OAuth2ServerConfig {

    @Bean
    public JwtAccessTokenConverter jwtAccessTokenConverter() {
        JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
        converter.setSigningKey("secret");
        return converter;
    }

    @Bean
    public TokenStore tokenStore(JwtAccessTokenConverter converter) {
        return new JwtTokenStore(converter);
    }

    @Bean
    public DefaultAccessTokenConverter accessTokenConverter() {
        return new DefaultAccessTokenConverter();
    }
}

七、使用Spring Security Test支持

Spring Security提供了测试支持，可以简化安全性集成测试的编写。

package cn.juwatech.controller;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.security.test.context.support.WithAnonymousUser;
import org.springframework.security.test.context.support.WithMockUser;
import org.springframework.test.web.servlet.MockMvc;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

@SpringBootTest
@AutoConfigureMockMvc
public class SecurityControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @Test
    @WithAnonymousUser
    public void testSecureEndpointWithoutAuthentication() throws Exception {
        mockMvc.perform(get("/secure-data"))
                .andExpect(status().isUnauthorized());
    }

    @Test
    @WithMockUser(authorities = "SCOPE_READ")
    public void testSecureEndpointWithAuthentication() throws Exception {
        mockMvc.perform(get("/secure-data"))
                .andExpect(status().isOk());
    }
}

八、总结

Spring Cloud Security为Spring Boot应用提供了一套完整的安全解决方案，支持OAuth2、JWT等多种认证和授权机制。通过简单的配置和代码注解，可以快速实现服务的安全性增强。同时，Spring Security的测试支持也简化了安全性集成测试的过程。
