//这里如果直接 return "WEB-INF/jsp/index"的话，由于默认转发，地址栏不变，还是http://localhost:8080/ssm_shiro_war_exploded/login
//仍然执行/login = anon过滤规则，不会执行下面的权限验证过滤规则 /**=user,roles[admin]
//因此需要使用重定向"redirect:index"，才能让 /**=user,roles[admin]过滤规则生效
return "redirect:index";
}
@RequestMapping("/index")
public String index() {
return "WEB-INF/jsp/index";
}
}
这里到dao service entity就不再粘贴代码了
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/ssm-shiro?useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8 jdbc.driverClass=com.mysql.cj.jdbc.Driver jdbc.user=root jdbc.password=root
applicationContext.xml
项目中用到的是通用mapper，实体类的类名和数据库的表名对应，实体类的属性和数据库表的字段名对应
测试
运行项目
因为我shiro过滤链配置的是只有角色为admin的能进首页，角色为user不能进首页，会被拦截（数据库jake为admin,tom为user）
运行结果：
