java学习爱好者 2019-05-27 16:21:00
开发环境:
1、mysql - 5.7.21
2、navicat(mysql客户端管理工具)
3、idea 2017
4、jdk9
5、tomcat 8.5
6、springboot
7、mybatis 3
8、shiro
9、maven
项目开始:
一、数据库设计:
注: 数据库三张表和spring整合shiro中的一模一样，在那边已经详细说明，这里直接大家看下三张表的ER图。

二、添加依赖，配置mybatis
1、用idea新建Spring Initializr项目，项目结构如下:

2、添加依赖:
<dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.3.2</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>provided</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-core</artifactId> <version>1.2.3</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>1.2.3</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.20</version> </dependency> <!--常用的工具包--> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> <version>3.4</version> </dependency> <!--spring的上下文工具包--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>4.1.7.RELEASE</version> </dependency> <!--对jsp的处理--> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-jasper</artifactId> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> </dependency> </dependencies>
3、application.properties
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource spring.datasource.driver-class-name=com.mysql.jdbc.Driver spring.datasource.url=jdbc:mysql:///# spring.datasource.username=# spring.datasource.password=# ## mybatis ## mybatis.mapper-locations=mappers/*.xml mybatis.type-aliases-package=com.zhu.shiro.entity ## 视图解析器 ## spring.mvc.view.prefix=/pages/ spring.mvc.view.suffix=.jsp
三、项目设计
注: spring整合shiro中是只有User实体类，在UserDao中定义了三个方法，通过表的关键关系查询Role和Permission;这里将采用另一种方式，三个实体类，设置实体类的关联关系。
1、entity层
User.java
public class User {
private Integer uid;
private String username;
private String password;
private Set<Role> roles = new HashSet<>();
}
Role.java
public class Role {
private Integer rid;
private String name;
private Set<Permission> permissions = new HashSet<>();
}
Permission.java
public class Permission {
private Integer pid;
private String name;
}
2、dao层
UserDao.java
public interface UserDao {
User findByUsername(String username);
}
UserDao.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.zhu.shiro.dao.UserDao">
<resultMap id="userMap" type="com.zhu.shiro.entity.User">
<id property="uid" column="uid"/>
<result property="username" column="user_name"/>
<result property="password" column="pass_word"/>
<collection property="roles" ofType="com.zhu.shiro.entity.Role">
<id property="rid" column="rid"/>
<result property="name" column="role_name"/>
<collection property="permissions" ofType="com.zhu.shiro.entity.Permission">
<id property="pid" column="pid"/>
<result property="name" column="permission_name"/>
</collection>
</collection>
</resultMap>
<select id="findByUsername" parameterType="string" resultMap="userMap">
SELECT *
FROM tb_user u,tb_role r,tb_permission p
WHERE u.rid=r.rid
AND p.rid=r.rid
AND u.user_name=#{username}
</select>
</mapper>
3、service层
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserDao userDao;
@Override
public User findByUsername(String username) {
return userDao.findByUsername(username);
}
}
4、junit测试
@RunWith(SpringRunner.class)
@SpringBootTest
public class UserServiceImplTest {
@Autowired
private UserService userService;
@Test
public void findByUsername() {
User u = userService.findByUsername("tom");
Set<Role> roleSet = u.getRoles();
for (Role role : roleSet){
Set<Permission> permissionSet = role.getPermissions();
for (Permission permission : permissionSet){
System.out.println(permission.getName());
}
System.out.println(role.getName());
}
}
}
运行结果:

数据库中tom是admin角色，有增删改查权限，符合预期，测试通过。
5、controller层
TestController.java
@Controller
public class TestController {
//用户登录
@RequestMapping("/loginUser")
public String loginUser(@RequestParam("username") String username,
@RequestParam("password") String password,
HttpSession session) {
//把前端输入的username和password封装为token
UsernamePasswordToken token = new UsernamePasswordToken(username, password);
Subject subject = SecurityUtils.getSubject();
try {
subject.login(token);
session.setAttribute("user", subject.getPrincipal());
return "index";
} catch (Exception e) {
return "login";
}
}
//退出登录
@RequestMapping("/logout")
public String logout() {
Subject subject = SecurityUtils.getSubject();
if (subject != null) {
subject.logout();
}
return "login";
}
//访问login时跳到login.jsp
@RequestMapping("/login")
public String login() {
return "login";
}
//admin角色才能访问
@RequestMapping("/admin")
@ResponseBody
public String admin() {
return "admin success";
}
//有delete权限才能访问
@RequestMapping("/edit")
@ResponseBody
public String edit() {
return "edit success";
}
@RequestMapping("/test")
@ResponseBody
@RequiresRoles("guest")
public String test(){
return "test success";
}
}
说明:这里用户登录方法用到了shiro，但是这里还没配置shiro，所以暂时不能使用，先搭起整个骨架，然后再加入shiro。
6、jsp页面
login.jsp
(登录页面)
%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>Login</title> </head> <body> <h1>欢迎登录！</h1> <form action="/loginUser" method="post"> <input type="text" name="username"><br> <input type="password" name="password"><br> <input type="submit" value="提交"> </form> </body> </html>
index.jsp
(登录成功跳转的页面)
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<h1>欢迎登录，${user.username}</h1>
</body>
</html>
unauthorized.jsp
(无权访问跳转的页面)
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>unauthorized</title> </head> <body> unauthorized! </body> </html>
现在说一下要求:
admin路由要求只有具有admin角色的用户才能访问，edit路由需要有delete权限的用户才能访问，test路由要guest角色才能访问，login、loginUser都不做拦截，本文讲解两种拦截方式，对test的拦截是在controller对应的方法上加注解，其他是拦截是写在shiro的配置类中。
预期分析:
tom是有admin角色和所有权限，所以用tom登录后，可以访问edit和admin，但是不能访问guest;
而cat是guest角色，只有create和query权限，所以不能访问admin和edit，但是可以访问guest。
四、配置shiro
由于springboot还没有集成shiro，所以不能直接在application.properties中配置，需要通过类的方式配置。
核心配置类:
ShiroConfiguration.java
@Configuration
public class ShiroConfiguration {
/**
* 密码校验规则HashedCredentialsMatcher
* 这个类是为了对密码进行编码的 ,
* 防止密码在数据库里明码保存 , 当然在登陆认证的时候 ,
* 这个类也负责对form里输入的密码进行编码
* 处理认证匹配处理器：如果自定义需要实现继承HashedCredentialsMatcher
*/
@Bean("hashedCredentialsMatcher")
public HashedCredentialsMatcher hashedCredentialsMatcher() {
HashedCredentialsMatcher credentialsMatcher = new HashedCredentialsMatcher();
//指定加密方式为MD5
credentialsMatcher.setHashAlgorithmName("MD5");
//加密次数
credentialsMatcher.setHashIterations(1024);
credentialsMatcher.setStoredCredentialsHexEncoded(true);
return credentialsMatcher;
}
@Bean("authRealm")
@DependsOn("lifecycleBeanPostProcessor")//可选
public AuthRealm authRealm(@Qualifier("hashedCredentialsMatcher") HashedCredentialsMatcher matcher) {
AuthRealm authRealm = new AuthRealm();
authRealm.setAuthorizationCachingEnabled(false);
authRealm.setCredentialsMatcher(matcher);
return authRealm;
}
/**
* 定义安全管理器securityManager,注入自定义的realm
* @param authRealm
* @return
*/
@Bean("securityManager")
public SecurityManager securityManager(@Qualifier("authRealm") AuthRealm authRealm) {
DefaultWebSecurityManager manager = new DefaultWebSecurityManager();
manager.setRealm(authRealm);
return manager;
}
/**
* 定义shiroFilter过滤器并注入securityManager
* @param manager
* @return
*/
@Bean("shiroFilter")
public ShiroFilterFactoryBean shiroFilter(@Qualifier("securityManager") SecurityManager manager) {
ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
//设置securityManager
bean.setSecurityManager(manager);
//设置登录页面
//可以写路由也可以写jsp页面的访问路径
bean.setLoginUrl("/login");
//设置登录成功跳转的页面
bean.setSuccessUrl("/pages/index.jsp");
//设置未授权跳转的页面
bean.setUnauthorizedUrl("/pages/unauthorized.jsp");
//定义过滤器
LinkedHashMap<String, String> filterChainDefinitionMap = new LinkedHashMap<>();
filterChainDefinitionMap.put("/index", "authc");
filterChainDefinitionMap.put("/login", "anon");
filterChainDefinitionMap.put("/loginUser", "anon");
filterChainDefinitionMap.put("/admin", "roles[admin]");
filterChainDefinitionMap.put("/edit", "perms[delete]");
filterChainDefinitionMap.put("/druid/**", "anon");
//需要登录访问的资源 , 一般将/**放在最下边
filterChainDefinitionMap.put("/**", "authc");
bean.setFilterChainDefinitionMap(filterChainDefinitionMap);
return bean;
}
/**
* Spring的一个bean , 由Advisor决定对哪些类的方法进行AOP代理 .
* @return
*/
@Bean
public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
DefaultAdvisorAutoProxyCreator creator = new DefaultAdvisorAutoProxyCreator();
creator.setProxyTargetClass(true);
return creator;
}
/**
* 配置shiro跟spring的关联
* @param securityManager
* @return
*/
@Bean
public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(@Qualifier("securityManager") SecurityManager securityManager) {
AuthorizationAttributeSourceAdvisor advisor = new AuthorizationAttributeSourceAdvisor();
advisor.setSecurityManager(securityManager);
return advisor;
}
/**
* lifecycleBeanPostProcessor是负责生命周期的 , 初始化和销毁的类
* (可选)
*/
@Bean("lifecycleBeanPostProcessor")
public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {
return new LifecycleBeanPostProcessor();
}
}
注:这个类每个bean的作用都已在代码中注释说明，这个类就相当于spring整合shiro的spring-shiro.xml中对shiro的配置。
自定义realm:
AutuRealm.java
public class AuthRealm extends AuthorizingRealm{
@Autowired
private UserService userService;
/**
* 为用户授权
* @param principals
* @return
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
//获取前端输入的用户信息，封装为User对象
User userweb = (User) principals.getPrimaryPrincipal();
//获取前端输入的用户名
String username = userweb.getUsername();
//根据前端输入的用户名查询数据库中对应的记录
User user = userService.findByUsername(username);
//如果数据库中有该用户名对应的记录，就进行授权操作
if (user != null){
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
//因为addRoles和addStringPermissions方法需要的参数类型是Collection
//所以先创建两个collection集合
Collection<String> rolesCollection = new HashSet<String>();
Collection<String> perStringCollection = new HashSet<String>();
//获取user的Role的set集合
Set<Role> roles = user.getRoles();
//遍历集合
for (Role role : roles){
//将每一个role的name装进collection集合
rolesCollection.add(role.getName());
//获取每一个Role的permission的set集合
Set<Permission> permissionSet = role.getPermissions();
//遍历集合
for (Permission permission : permissionSet){
//将每一个permission的name装进collection集合
perStringCollection.add(permission.getName());
}
//为用户授权
info.addStringPermissions(perStringCollection);
}
//为用户授予角色
info.addRoles(rolesCollection);
return info;
}else{
return null;
}
}
/**
* 认证登录
* @param token
* @return
* @throws AuthenticationException
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
//token携带了用户信息
UsernamePasswordToken usernamePasswordToken = (UsernamePasswordToken) token;
//获取前端输入的用户名
String userName = usernamePasswordToken.getUsername();
//根据用户名查询数据库中对应的记录
User user = userService.findByUsername(userName);
//当前realm对象的name
String realmName = getName();
//盐值
ByteSource credentialsSalt = ByteSource.Util.bytes(user.getUsername());
//封装用户信息，构建AuthenticationInfo对象并返回
AuthenticationInfo authcInfo = new SimpleAuthenticationInfo(user, user.getPassword(),credentialsSalt, realmName);
return authcInfo;
}
}
注:这个类也有详细的注释说明。
这样就完成了springboot对shiro的整合，接下来就可以进行测试了！
五、测试
tom登录
图片发自简书App
图片发自简书App
tom访问admin
图片发自简书App
tom访问test
图片发自简书App
cat登录
图片发自简书App
cat访问admin
图片发自简书App
cat访问test
图片发自简书App
测试结果与预期相符，测试通过，springboot整合shiro成功！
特别说明:
由于设置了MD5加密，所以数据库中存储的用户密码应该是加密后的密文，否则在登录页面输入明文会验证不通过。假如1234的密文为asdfghjkl，数据库中存储的应该是asdfghjkl，在登录时输入1234就能验证通过。
附上明文转密文的代码:
public static void main(String[] args) {
String hashAlgorithName = "MD5";
String password = "登录时输入的密码";
int hashIterations = 1024;//加密次数
ByteSource credentialsSalt = ByteSource.Util.bytes("登录时输入的用户名");
Object obj = new SimpleHash(hashAlgorithName, password, credentialsSalt, hashIterations);
System.out.println(obj);
}
若不使用MD5加密
1、添加一个类
public class CredenttiaMatcher extends SimpleCredentialsMatcher{
@Override
public boolean doCredentialsMatch(AuthenticationToken token, AuthenticationInfo info) {
UsernamePasswordToken usernamePasswordToken = (UsernamePasswordToken) token;
String password = new String(usernamePasswordToken.getPassword());
String dbPassword = (String) info.getCredentials();
return this.equals(password,dbPassword);
}
}
2、将ShiroConfiguration.java中名为"hashedCredentialsMatcher"的bean替换成:
*@Bean("credenttiaMatcher")
public CredenttiaMatcher credenttiaMatcher() {
return new CredenttiaMatcher();
}
将名为"authRealm"的bean替换成:
@Bean("authRealm")
@DependsOn("lifecycleBeanPostProcessor")//可选
public AuthRealm authRealm(@Qualifier("credenttiaMatcher") CredenttiaMatcher matcher) {
AuthRealm authRealm = new AuthRealm();
authRealm.setCredentialsMatcher(matcher);
return authRealm;
}
3、AuthRealm.java中的doGetAuthenticationInfo方法里面的内容替换成:
//=========================未加密版========================== //token携带了用户登录的信息 UsernamePasswordToken usernamePasswordToken = (UsernamePasswordToken) token; //获取前端输入的用户名 String username = usernamePasswordToken.getUsername(); //根据前端输入的用户名查询数据库中的记录 User user = userService.findByUsername(username); //校验密码，验证登录 return new SimpleAuthenticationInfo(user,user.getPassword(),this.getClass().getName());
完成以上3步就去掉了MD5加密。
