spring boot整合CAS配置详解

在下不才，以下是我花了好几天的时间才整合出来的在spring boot里面的cas配置整合

为了帮助没搞定的人，毕竟自己踩了很多坑，一步一步爬过来的，有什么不足之处可以给建议  谢谢（小部分代码是整合他人的）

1.不多废话，直接上最重要的代码，以下代码整合cas的重要过程

2.为了让你们更省力且直接的看到效果，我把相关配置也贴出来

import org.springframework.boot.context.properties.configurationproperties; 
import org.springframework.context.annotation.configuration; 
 
import java.util.arrays; 
import java.util.list; 
 
@configurationproperties(prefix = "spring.cas") 
public class springcasautoconfig { 
 
  static final string separator = ","; 
 
  private string validatefilters; 
  private string signoutfilters; 
  private string authfilters; 
  private string assertionfilters; 
  private string requestwrapperfilters; 
 
  private string casserverurlprefix; 
  private string casserverloginurl; 
  private string servername; 
  private boolean usesession = true; 
  private boolean redirectaftervalidation = true; 
 
  public list<string> getvalidatefilters() { 
    return arrays.aslist(validatefilters.split(separator)); 
  } 
  public void setvalidatefilters(string validatefilters) { 
    this.validatefilters = validatefilters; 
  } 
  public list<string> getsignoutfilters() { 
    return arrays.aslist(signoutfilters.split(separator)); 
  } 
  public void setsignoutfilters(string signoutfilters) { 
    this.signoutfilters = signoutfilters; 
  } 
  public list<string> getauthfilters() { 
    return arrays.aslist(authfilters.split(separator)); 
  } 
  public void setauthfilters(string authfilters) { 
    this.authfilters = authfilters; 
  } 
  public list<string> getassertionfilters() { 
    return arrays.aslist(assertionfilters.split(separator)); 
  } 
  public void setassertionfilters(string assertionfilters) { 
    this.assertionfilters = assertionfilters; 
  } 
  public list<string> getrequestwrapperfilters() { 
    return arrays.aslist(requestwrapperfilters.split(separator)); 
  } 
  public void setrequestwrapperfilters(string requestwrapperfilters) { 
    this.requestwrapperfilters = requestwrapperfilters; 
  } 
  public string getcasserverurlprefix() { 
    return casserverurlprefix; 
  } 
  public void setcasserverurlprefix(string casserverurlprefix) { 
    this.casserverurlprefix = casserverurlprefix; 
  } 
  public string getcasserverloginurl() { 
    return casserverloginurl; 
  } 
  public void setcasserverloginurl(string casserverloginurl) { 
    this.casserverloginurl = casserverloginurl; 
  } 
  public string getservername() { 
    return servername; 
  } 
  public void setservername(string servername) { 
    this.servername = servername; 
  } 
  public boolean isredirectaftervalidation() { 
    return redirectaftervalidation; 
  } 
  public void setredirectaftervalidation(boolean redirectaftervalidation) { 
    this.redirectaftervalidation = redirectaftervalidation; 
  } 
  public boolean isusesession() { 
    return usesession; 
  } 
  public void setusesession(boolean usesession) { 
    this.usesession = usesession; 
  } 
 
} 

3.配置文件  dev.yml

  #cas client config 
  spring:cas: 
  sign-out-filters: /logout 
  auth-filters: /* 
  validate-filters: /* 
  request-wrapper-filters: /* 
  assertion-filters: /* 
  cas-server-login-url: cas登录url 
  cas-server-url-prefix:cas登录域名 
  redirect-after-validation: true 
  use-session: true 
  server-name: http://localhost:8080
