CAS 5.3.1系列之客户端对接（五）

我们要接入客户端可以常用第三方的库cas-client-autoconfig-support来对接，比较快捷，迅速实现，或者可以用cas-client-support-springboot集成到boot项目

pom配置：

<!-- CAS依赖包 --> <dependency> <groupId>net.unicon.cas</groupId> <artifactId>cas-client-autoconfig-support</artifactId> <version>1.5.0-GA</version> </dependency>

application.yml配置：

cas: server-login-url: http://127.0.0.1:8080/cas/login server-url-prefix: http://127.0.0.1:8080/cas client-host-url: http://127.0.0.1:8082

可以自定义一个重定向策略类，这里还是和默认的策略一样，可以根据项目需要自行更改

package org.muses.jeeplatform.oa.cas; import org.jasig.cas.client.authentication.AuthenticationRedirectStrategy; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.io.IOException; public class CustomAuthticationRedirectStrategy implements AuthenticationRedirectStrategy { @Override public void redirect(HttpServletRequest request, HttpServletResponse response, String potentialRedirectUrl) throws IOException { // response.setCharacterEncoding("utf-8"); // response.setContentType("application/json; charset=utf-8"); // PrintWriter out = response.getWriter(); // out.write("401"); //response重定向 response.sendRedirect(potentialRedirectUrl); } }

然后通过配置类，实现CasClientConfigurerAdapter类，记得配置类要加上@EnableCasClient注解，开启CAS支持：

package org.muses.jeeplatform.oa.config; import net.unicon.cas.client.configuration.CasClientConfigurerAdapter; import net.unicon.cas.client.configuration.EnableCasClient; import org.jasig.cas.client.authentication.AuthenticationFilter; import org.springframework.boot.web.servlet.FilterRegistrationBean; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import java.util.HashMap; import java.util.Map; /** * <pre> * CAS配置类 * </pre> * * @author nicky * <pre> * 修改记录 * 修改后版本: 修改人： 修改日期: 2020年04月11日 修改内容: * </pre> */ @Configuration @EnableCasClient public class CASConfig extends CasClientConfigurerAdapter { private static final String CAS_SERVER_URL_LOGIN = "http://127.0.0.1:8080/cas/login"; private static final String SERVER_NAME = "http://127.0.0.1:8082/"; private static final String AUTHENTICATION_REDIRECT_STRATEGY_CLASS = "org.muses.jeeplatform.oa.cas.CustomAuthticationRedirectStrategy"; @Override public void configureAuthenticationFilter(FilterRegistrationBean authenticationFilter) { super.configureAuthenticationFilter(authenticationFilter); authenticationFilter.getInitParameters().put("authenticationRedirectStrategyClass",AUTHENTICATION_REDIRECT_STRATEGY_CLASS); } @Override public void configureValidationFilter(FilterRegistrationBean validationFilter) { Map<String, String> initParameters = validationFilter.getInitParameters(); initParameters.put("encodeServiceUrl", "false"); } @Bean public FilterRegistrationBean filterRegistrationBean(){ FilterRegistrationBean registrationBean = new FilterRegistrationBean(); registrationBean.setFilter(new AuthenticationFilter()); registrationBean.addUrlPatterns("/*"); Map<String, String> initParameters = new HashMap<String,String>(4); initParameters.put("casServerLoginUrl",CAS_SERVER_URL_LOGIN); initParameters.put("serverName",SERVER_NAME); initParameters.put("ignorePattern","/logoutSuccess/*"); // 自定义重定向策略 initParameters.put("authenticationRedirectStrategyClass", AUTHENTICATION_REDIRECT_STRATEGY_CLASS); registrationBean.setInitParameters(initParameters); registrationBean.setOrder(1); return registrationBean; } }

访问项目时候，如果没登录过，会跳到CAS进行认证授权，授权通过才会返回主页
