Shiro+Cas微服务化及前后端完全分离攻略
本攻略将详细讲解如何使用Shiro+Cas实现微服务化及前后端完全分离,包括实现过程、使用方法、示例说明。
实现过程
1. 添加依赖
在pom.xml
文件中添加以下依赖:
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring-boot-web-starter</artifactId>
<version>1.7.1</version>
</dependency>
<dependency>
<groupId>org.jasig.cas.client</groupId>
<artifactId>cas-client-core</artifactId>
<version>3.6.0</version>
</dependency>
2. 配置Shiro
在application.yml
文件中配置Shiro,例如:
shiro:
cas:
server-url-prefix: https://cas.example.com:8443/cas
service: http://localhost:8080/cas
redirect-after-logout: true
logout-url-patterns: /logout
filter-chain-definition-map:
/logout: anon
/static/**: anon
/login: anon
/api/**: authc
/**: user
3. 配置Cas
在application.yml
文件中配置Cas,例如:
cas:
server:
prefix: https://cas.example.com:8443/cas
client:
prefix: http://localhost:8080/cas
login-url: /login
logout-url: /logout
redirect-after-logout: true
gateway: true
use-session: false
4. 实现CasFilter
实现一个CasFilter,用于在请求头中添加Token参数,例如:
@Component
public class CasFilter extends AbstractCasFilter {
@Override
protected void doFilter(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
String token = request.getHeader("Token");
if (StringUtils.isNotBlank(token)) {
request.setAttribute("Token", token);
}
filterChain.doFilter(request, response);
}
}
5. 示例说明
以下是两个示例说明,分别演示了如何使用Shiro+Cas实现微服务化及前后端完全分离。
