NEW->Spring Starter Project->此版此时默认是2.1.8
勾上JDBC API
MyBatis Framework
MySQL Driver
Spring Web
Thymeleaf
快速搭建好SpringBoot,中间红叉、maven什么的详见：

即可
因为加了MyBatis，所以先在application.properties（此版此时默认生成的）里加上
spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8
spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver
spring.datasource.username=root
spring.datasource.password=
创建一个Controller试试：
@RestController
public class HelloController {
@RequestMapping("/hello")
public String hello() {
return "hello";
}
}
浏览器：http://localhost:8080/hello
页面：hello
用Mybatis连数据库建个Mapper试试：
@Mapper
public interface TestDAO {
//数据库username字段不能有重值，纯技术快速跑通，起码应该是下面那个接口的样子
@Select("select password from user where username = #{username}")
public String getPassword(String username);
// @Select("select username,password from user where username = #{username}")
// public List<Map<String,String>> getPasswords(String username);
}
在Controller中注入即可：
@RestController
public class HelloController {
@Autowired
private TestDAO testDAO;
@RequestMapping("/hello")
public String hello() {
//aa能跑通变成变量即可
String password=testDAO.getPassword("aa");
// List<Map<String,String>> map=testDAO.getPasswords("aa");
return password;
}
}
纯技术跑通SpringBoot+Mybatis后再加上Shiro
数据库略
先用官方给的Quickstart试试：

// The easiest way to create a Shiro SecurityManager with configured

// accessible as a JVM singleton. Most applications wouldn't do this
// and instead rely on their container configuration or web.xml for
// webapps. That is outside the scope of this simple quickstart, so
// we'll just do the bare minimum so you can continue to get a feel
// for things.
SecurityUtils.setSecurityManager(securityManager);

需要在src/main/resources下创建一个shiro.ini(这里先用官方给的例子):

OK，没问题，下面从连数据库表中读取一些自定义权限
后面好像没有什么可视化的操作步骤了，找了个现成的例子：
先建个@Configuration，主要是把自己main的方式交给了Spring
package com.example.demo.config;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import com.example.demo.shiro.CustomRealm;
import java.util.LinkedHashMap;
import java.util.Map;
import org.apache.shiro.mgt.SecurityManager;
@Configuration
public class ShiroConfig {
@Bean
public ShiroFilterFactoryBean shirFilter(SecurityManager securityManager) {
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
// 必须设置 SecurityManager
shiroFilterFactoryBean.setSecurityManager(securityManager);
// setLoginUrl 如果不设置值，默认会自动寻找Web工程根目录下的"/login.jsp"页面 或 "/login" 映射
shiroFilterFactoryBean.setLoginUrl("/notLogin");
// 设置无权限时跳转的 url;
shiroFilterFactoryBean.setUnauthorizedUrl("/notRole");
// 设置拦截器
Map<String, String> filterChainDefinitionMap = new LinkedHashMap<>();
//游客，开发权限
filterChainDefinitionMap.put("/guest/**", "anon");
//用户，需要角色权限 “user”
filterChainDefinitionMap.put("/user/**", "roles[user]");
//管理员，需要角色权限 “admin”
filterChainDefinitionMap.put("/admin/**", "roles[admin]");
//开放登陆接口
filterChainDefinitionMap.put("/login", "anon");
//其余接口一律拦截
//主要这行代码必须放在所有权限设置的最后，不然会导致所有 url 都被拦截
filterChainDefinitionMap.put("/**", "authc");
shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
System.out.println("Shiro拦截器工厂类注入成功");
return shiroFilterFactoryBean;
}
/**
* 注入 securityManager
*/
@Bean
public SecurityManager securityManager() {
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
// 设置realm.
securityManager.setRealm(customRealm());
return securityManager;
}
/**
* 自定义身份认证 realm;
* <p>
* 必须写这个类，并加上 @Bean 注解，目的是注入 CustomRealm，
* 否则会影响 CustomRealm类 中其他类的依赖注入
*/
@Bean
public CustomRealm customRealm() {
return new CustomRealm();
}
}
需要一个权限类Realm(域)继承AuthorizingRealm实现下面的方法：
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
// TODO Auto-generated method stub
return null;
}
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
// TODO Auto-generated method stub
return null;
}
实例如下：
package com.example.demo.shiro;
import java.util.HashSet;
import java.util.Set;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.AccountException;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.springframework.beans.factory.annotation.Autowired;
import com.example.demo.dao.TestDAO;
public class CustomRealm extends AuthorizingRealm {
//这里省事就把UserMapper改成了TestDAO
private TestDAO userMapper;
@Autowired
private void setUserMapper(TestDAO userMapper) {
this.userMapper = userMapper;
}
/**
* 获取身份验证信息 Shiro中，最终是通过 Realm 来获取应用程序中的用户、角色及权限信息的。
*
* @param authenticationToken 用户身份信息 token
* @return 返回封装了用户信息的 AuthenticationInfo 实例
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken)
throws AuthenticationException {
System.out.println("————身份认证方法————");
UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken;
// 从数据库获取对应用户名密码的用户
String password = userMapper.getPassword(token.getUsername());
if (null == password) {
throw new AccountException("用户名不正确");
} else if (!password.equals(new String((char[]) token.getCredentials()))) {
throw new AccountException("密码不正确");
}
return new SimpleAuthenticationInfo(token.getPrincipal(), password, getName());
}
/**
* 获取授权信息
*
* @param principalCollection
* @return
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("————权限认证————");
String username = (String) SecurityUtils.getSubject().getPrincipal();
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
// 获得该用户角色
// String role = userMapper.getRole(username);
//这里用了另一个表通过ID查找仅为快速跑通，通了后面怎么改怎么有
//TestDAO中加入下面两名
//@Select("select role from role where id = #{id}")
//public String getRole(int id);
String role = userMapper.getRole(1);
Set<String> set = new HashSet<>();
// 需要将 role 封装到 Set 作为 info.setRoles() 的参数
set.add(role);
// 设置该用户拥有的角色
info.setRoles(set);
return info;
}
}
这时再访问http://localhost:8080/hello时拦截已生效
http://localhost:8080/notLogin;jsessionid=D9E0F7104B7AA126E73835727E94C2EB
页面：Whitelabel Error Page 404
在HelloController中加个login方法试试：
@RequestMapping(value = "/login")
public String login(String username, String password) {
// 从SecurityUtils里边创建一个 subject
Subject subject = SecurityUtils.getSubject();
// 在认证提交前准备 token（令牌）
UsernamePasswordToken token = new UsernamePasswordToken(username, password);
// 执行认证登陆
subject.login(token);
// 根据权限，指定返回数据
String role = testDAO.getRole(1);
if ("user".equals(role)) {
return "欢迎登陆";
}
if ("admin".equals(role)) {
return "欢迎来到管理员页面";
}
return "权限错误！";
}
浏览器：http://localhost:8080/login?username=aa&password=aa2
页面：欢迎来到管理员页面
