SpringBoot学习记录:@Cacheable不起作用 -->原因:Shrio + @Cache整合

问题描述:

1、在使用shiro的项目中,整合Cache,@Cacheable失效

2、去掉ShiroConfig后,@Cacheable能够最长使用,其他注解也OK

问题原因:

@Cacheable ,当使用ehcache时,autoconfig机制会根据配置文件自动去初始化bean

而shiroConfig在@Configuration构造时,也会去初始化ehcache ,项目启动会产生如下异常

解决方法:

realm原始代码(错误):

public class UserRealm extends AuthorizingRealm {
    @Autowired
    private AdminService adminService;
    @Autowired
    private CadreService cadreService;
    @Autowired
    private ParticipantService participantService;
    @Autowired
    private VoteService voteService;

    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {……}

    //认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {……}
}

在realm的自动注入下加@Lezy注解,问题解决

public class UserRealm extends AuthorizingRealm {
    @Autowired
    private AdminService adminService;
    @Autowired
    private CadreService cadreService;
    @Autowired
    private ParticipantService participantService;
    @Autowired
    private VoteService voteService;

    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {……}

    //认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {……}
}
