CAS 5.3.1系列之客户端对接（五）

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;

@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; }


}
