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

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@Lazy注解，问题解决

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

    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {……}

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