CAS学习记录4--CAS,Spring MVC,Shiro整合

我不是女神ヾ 2022-05-19 00:14 224阅读 0赞

一、前言

前一节介绍Servlet配置方式，本节介绍比较实用的部分，CAS与Spring MVC，Shiro的整合

二、项目配置

之前已经建好test3的模组，现在就在它上面配

首先是CA证书，将之前生成的证书复制过去

打开pom.xml文件，修改配置如下，比较简单，就不说明了

打开WEB-INF/web.xml修改配置如下，有的文章说Shiro配置要在Spring MVC配置之前，实际上是没有关系的，因为web.xml 的加载顺序是：context-param -> listener -> filter -> servlet

1.  `<?xml version="1.0" encoding="UTF-8"?>`
2.  `<web-app xmlns="http://java.sun.com/xml/ns/javaee"`
3.  `xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"`

先发个整体项目图

![20170726155437780][]

在resources目录下新建spring-mvc.xml

在resources目录下新建applicationContext-web.xml

在resources目录下新建applicationContext-shiro.xml，主要是login和logout两个过滤器

1.  `<?xml version="1.0" encoding="UTF-8"?>`
2.  `<beans xmlns="http://www.springframework.org/schema/beans"`
3.  `xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"`

56. ``
57. `<property name="casService" value="${shiro.cas.service}" />`
58. `</bean>`
59. `</beans>`

在resources目录下新建shiro.properties

1.  `#shiro`
2.  `shiro.loginUrl=https://localhost:9001/cas/login?service=https://localhost:9004/test3/login`
3.  `shiro.logoutUrl=https://localhost:9001/cas/logout?service=https://localhost:9004/test3/login`
4.  `shiro.cas.serverUrlPrefix=https://localhost:9001/cas`
5.  `shiro.cas.service=https://localhost:9004/test3/login`
6.  `shiro.failureUrl=/error`
7.  `shiro.successUrl=/success`

接下来是几个类建立

在com.test.controller包下新建LoginController.java，不解释

1.  `package com.test.controller;`
2.   
3.  `import org.slf4j.Logger;`
4.  `import org.slf4j.LoggerFactory;`
5.  `import org.springframework.stereotype.Controller;`
6.  `import org.springframework.web.bind.annotation.RequestMapping;`
7.   
8.  `@Controller`
9.  `public class LoginController {`
10. `private static final Logger logger = LoggerFactory.getLogger(LoginController.class);`
11.  
12. `@RequestMapping("/success")`
13. `public String success(){`
14. `logger.info("登录成功");`
15. `return "success";`
16. `}`
17.  
18. `@RequestMapping("/error")`
19. `public String error(){`
20. `logger.info("登录失败");`
21. `return "error";`
22. `}`
23. `}`

在com.test.security包下新建Principal.java，这个用于保存账号登录信息

1.  `package com.test.security;`
2.   
3.  `import java.io.Serializable;`
4.   
5.  `public class Principal implements Serializable {`
6.   
7.  `private static final long serialVersionUID = -6577595270150512805L;`
8.   
9.  `private String id;`
10. `private String userName;`
11. `private String trueName;`
12. `private String email;`
13. `private boolean superUser;`
14.  
15. `public Principal(String id, String userName, String trueName, String email) {`
16. `this.id = id;`
17. `this.userName = userName;`
18. `this.trueName = trueName;`
19. `this.email = email;`
20. `}`
21.  
22. `public String getId() {`
23. `return id;`
24. `}`
25.  
26. `public void setId(String id) {`
27. `this.id = id;`
28. `}`
29.  
30. `public String getUserName() {`
31. `return userName;`
32. `}`
33.  
34. `public void setUserName(String userName) {`
35. `this.userName = userName;`
36. `}`
37.  
38. `public String getTrueName() {`
39. `return trueName;`
40. `}`
41.  
42. `public void setTrueName(String trueName) {`
43. `this.trueName = trueName;`
44. `}`
45.  
46. `public String getEmail() {`
47. `return email;`
48. `}`
49.  
50. `public void setEmail(String email) {`
51. `this.email = email;`
52. `}`
53.  
54. `public boolean isSuperUser() {`
55. `return superUser;`
56. `}`
57.  
58. `public void setSuperUser(boolean superUser) {`
59. `this.superUser = superUser;`
60. `}`
61.  
62. `}`

在com.test.security包下新建ShiroDbRealm.java，这个用于自定义登录验证及权限验证

1.  `package com.test.security;`
2.   
3.  `import org.apache.shiro.authc.AuthenticationException;`
4.  `import org.apache.shiro.authc.AuthenticationInfo;`
5.  `import org.apache.shiro.authc.AuthenticationToken;`
6.  `import org.apache.shiro.authc.SimpleAuthenticationInfo;`
7.  `import org.apache.shiro.authz.AuthorizationInfo;`
8.  `import org.apache.shiro.authz.SimpleAuthorizationInfo;`
9.  `import org.apache.shiro.cas.CasAuthenticationException;`
10. `import org.apache.shiro.cas.CasToken;`
11. `import org.apache.shiro.subject.PrincipalCollection;`
12. `import org.apache.shiro.subject.SimplePrincipalCollection;`
13. `import org.apache.shiro.util.StringUtils;`
14. `import org.jasig.cas.client.authentication.AttributePrincipal;`
15. `import org.jasig.cas.client.validation.Assertion;`
16. `import org.jasig.cas.client.validation.TicketValidationException;`
17. `import org.jasig.cas.client.validation.TicketValidator;`
18. `import org.slf4j.Logger;`
19. `import org.slf4j.LoggerFactory;`
20.  
21. `import java.util.ArrayList;`
22. `import java.util.List;`
23. `import java.util.Map;`
24.  
25. `public class ShiroDbRealm extends org.apache.shiro.cas.CasRealm {`
26. `private static Logger log = LoggerFactory.getLogger(ShiroDbRealm.class);`
27.  
28. `/**`
29. `* 设置权限信息`
30. `*/`
31. `@Override`
32. `protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {`
33. `Principal principal = (Principal) principals.getPrimaryPrincipal();`
34. `if (principal == null) {`
35. `return null;`
36. `}`
37. `SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();`
38. `// TODO:权限获取`
39. `List<String> permissions = new ArrayList();`
40. `permissions.add("...");`
41. `simpleAuthorizationInfo.addStringPermissions(permissions);`
42. `return simpleAuthorizationInfo;`
43. `}`
44.  
45.  
46. `/**`
47. `* 在原CasRealm方法上做调整`
48. `* @param token`
49. `* @return`
50. `* @throws AuthenticationException`
51. `*/`
52. `@Override`
53. `protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {`
54. `CasToken casToken = (CasToken)token;`
55. `if(token == null) {`
56. `return null;`
57. `} else {`
58. `String ticket = (String)casToken.getCredentials();`
59. `if(!StringUtils.hasText(ticket)) {`
60. `return null;`
61. `} else {`
62. `TicketValidator ticketValidator = this.ensureTicketValidator();`
63.  
64. `try {`
65. `Assertion e = ticketValidator.validate(ticket, this.getCasService());`
66. `AttributePrincipal casPrincipal = e.getPrincipal();`
67. `String userId = casPrincipal.getName();`
68. `log.debug("Validate ticket : {} in CAS server : {} to retrieve user : {}", new Object[]{ticket, this.getCasServerUrlPrefix(), userId});`
69. `Map attributes = casPrincipal.getAttributes();`
70. `casToken.setUserId(userId);`
71. `String rememberMeAttributeName = this.getRememberMeAttributeName();`
72. `String rememberMeStringValue = (String)attributes.get(rememberMeAttributeName);`
73. `boolean isRemembered = rememberMeStringValue != null && Boolean.parseBoolean(rememberMeStringValue);`
74. `if(isRemembered) {`
75. `casToken.setRememberMe(true);`
76. `}`
77.  
78. `//List principals = CollectionUtils.asList(new Object[]{userId, attributes});`
79. `//使用自定义的Principal`
80. `Principal principals=new Principal("id", userId, "trueName", "email");`
81. `SimplePrincipalCollection principalCollection = new SimplePrincipalCollection(principals, this.getName());`
82. `return new SimpleAuthenticationInfo(principalCollection, ticket);`
83. `} catch (TicketValidationException var14) {`
84. `throw new CasAuthenticationException("Unable to validate ticket [" + ticket + "]", var14);`
85. `}`
86. `}`
87. `}`
88. `}`
89. `}`

还剩两个简单的jsp页面

在WEB-INF/view下新建success.jsp

1.  `<%@ page contentType="text/html;charset=UTF-8" language="java" %>`
2.  `<%@ taglib prefix="shiro" uri="http://shiro.apache.org/tags" %>`
3.  `<html>`
4.  `<head>`
5.  `<title></title>`
6.  `</head>`
7.  `<body>`
8.  `<h1>success</h1>`
9.  `<shiro:principal property="userName"/>`
10. `<a href="https://localhost:9004/test3/logout">单点登出</a>`
11. `</body>`
12. `</html>`

在WEB-INF/view下新建error.jsp

1.  `<%@ page contentType="text/html;charset=UTF-8" language="java" %>`
2.  `<html>`
3.  `<head>`
4.  `<title></title>`
5.  `</head>`
6.  `<body>`
7.  `<h1>error</h1>`
8.  `</body>`
9.  `</html>`

到这边就可以启动Tomcat看效果了，在引用Shiro的CAS相关类的时候会提示过期，因为Shiro把各种协议都整合到一个新包去了

三、小结

整合完成了，不算复杂，CAS Server比较吃内存，可以调大点，CAS Client也可以下载源码来打包
