一、创建一个SpringBoot项目

点击Finish完成创建！

二、整合shiro

项目目录截图

1、pom.xml 添加shiro包

	<dependency>
        <groupId>org.apache.shiro</groupId>
        <artifactId>shiro-spring</artifactId>
        <version>1.3.2</version>
    </dependency>

2、Permissions.java(权限实体类)

public class Permissions {
    private String id;
    private String permissionsName;

    public String getId() { return id; }
    public void setId(String id) {   this.id = id;   }
    public String getPermissionsName() {  return permissionsName; }
    public void setPermissionsName(String permissionsName) {   this.permissionsName = permissionsName;  }
    public Permissions(String id, String permissionsName) {
        this.id = id;
        this.permissionsName = permissionsName;
    }
}

3、Role.java(角色实体类)

import java.util.Set;

public class Role {
    private String id;
    private String roleName;
    private Set<Permissions> permissions;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getRoleName() {
        return roleName;
    }

    public void setRoleName(String roleName) {
        this.roleName = roleName;
    }

    public Set<Permissions> getPermissions() {
        return permissions;
    }

    public void setPermissions(Set<Permissions> permissions) {
        this.permissions = permissions;
    }

    public Role(String id, String roleName, Set<Permissions> permissions) {
        this.id = id;
        this.roleName = roleName;
        this.permissions = permissions;
    }

}

下面要自己加上Set\get方法哦

4、user.java(用户实体类)

import java.util.Set;

public class User {
    private String id;
    private String userName;
    private String password;
    private Set<Role> roles;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public Set<Role> getRoles() {
        return roles;
    }

    public void setRoles(Set<Role> roles) {
        this.roles = roles;
    }

    public User(String id, String userName, String password, Set<Role> roles) {
        this.id = id;
        this.userName = userName;
        this.password = password;
        this.roles = roles;
    }
}

5、shiroConfig.java(shiro控制器)

import com.example.demo1209.shiro.CustomRealm;
import org.apache.shiro.mgt.SecurityManager;
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 java.util.LinkedHashMap;
import java.util.Map;
@Configuration
public class shiroConfig {
    @Bean(name = "shiroFilter")
    public ShiroFilterFactoryBean shiroFilter(SecurityManager securityManager) {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        shiroFilterFactoryBean.setLoginUrl("/login");
        shiroFilterFactoryBean.setUnauthorizedUrl("/notRole");
        Map<String, String> filterChainDefinitionMap = new LinkedHashMap<>();
        // <!-- authc:所有url都必须认证通过才可以访问; anon:所有url都都可以匿名访问-->
        filterChainDefinitionMap.put("/webjars/**", "anon");
        filterChainDefinitionMap.put("/login", "anon");
        filterChainDefinitionMap.put("/", "anon");
        filterChainDefinitionMap.put("/front/**", "anon");
        filterChainDefinitionMap.put("/api/**", "anon");
        filterChainDefinitionMap.put("/admin/**", "authc");
        filterChainDefinitionMap.put("/user/**", "authc");
        //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 剩余的都需要认证
        filterChainDefinitionMap.put("/**", "authc");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
        return shiroFilterFactoryBean;
    }
    @Bean
    public SecurityManager securityManager() {
        DefaultWebSecurityManager defaultSecurityManager = new DefaultWebSecurityManager();
        defaultSecurityManager.setRealm(customRealm());
        return defaultSecurityManager;
    }
    @Bean
    public CustomRealm customRealm() {
        CustomRealm customRealm = new CustomRealm();
        return customRealm;
    }
}

    @ResponseBody
    public String defaultLogin() {
        return "首页";
    }

    @RequestMapping(value = "/login", method = RequestMethod.POST)
    @ResponseBody
    public String login(@RequestParam("username") String username, @RequestParam("password") 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
        try {
            subject.login(token);
        } catch (UnknownAccountException uae) {
            return "未知账户";
        } catch (IncorrectCredentialsException ice) {
            return "密码不正确";
        } catch (LockedAccountException lae) {
            return "账户已锁定";
        } catch (ExcessiveAttemptsException eae) {
            return "用户名或密码错误次数过多";
        } catch (AuthenticationException ae) {
            return "用户名或密码不正确！";
        }
        if (subject.isAuthenticated()) {
            return "登录成功";
        } else {

     * @return
     */
    private User getMapByName(String userName){
        //共添加两个用户，两个用户都是admin一个角色，
