在web.xml中配置filter

<!-- 配置 shiro的filter-->
    <filter>
        <filter-name>shiroFilter</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>shiroFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

配置applicationContext-shiro.xml文件

基于shiro登录的部分核心代码

        // 基于shiro实现登录
        Subject subject = SecurityUtils.getSubject();
        AuthenticationToken authenticationToken = new UsernamePasswordToken(model.getUsername(), model.getPassword());
        
        try {
            subject.login(authenticationToken);
            return SUCCESS;
        } catch (AuthenticationException e) {
            //登录失败
            e.printStackTrace();
            return "login";
        }

realm类

@Service("bosRealm")
public class BosRealm extends AuthorizingRealm{
    @Autowired
    private UserService userService;
    @Autowired
    private RoleService roleService;
    @Autowired
    private PermissionService permissionService;
    //授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection pc) {
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        //根据当前登录的用户查询对应角色和权限
        Subject subject = SecurityUtils.getSubject();
        User user = (User) subject.getPrincipal();
        //查询角色
        List<Role> roles = roleService.findByUser(user);
        for (Role role : roles) {
            authorizationInfo.addRole(role.getKeyword());
        }
        //查询权限
        List<Permission> permissions = permissionService.findByUser(user);
        for (Permission permission : permissions) {
            authorizationInfo.addStringPermission(permission.getKeyword());
        }
        return authorizationInfo;
    }
    //认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        //转换taken
        UsernamePasswordToken passwordToken = (UsernamePasswordToken) token;
        //根据用户名查询用户信息
        User user = userService.findByUsername(passwordToken.getUsername());
        if(user == null) {
            //用户名不存在,
            return null;
        }else {
            //用户名存在
            //当用户返回密码时,securityManager安全管理器,自动比较返回密码和用户输入密码是否一致,
            //密码一致.登录成功,密码不一致,报出异常
            return new SimpleAuthenticationInfo(user, user.getPassword(), getName());
        }
    }
