SpringBoot學習記錄：@Cacheable不起作用 -->原因：Shiro + @Cache整合

SpringBoot學習記錄：@Cacheable不起作用 -->原因：Shrio + @Cache整合

問題描述：

1、在使用shiro的項目中，整合Cache，@Cacheable失效

2、去掉ShiroConfig后，@Cacheable能夠最長使用，其他注解也OK

問題原因：

@Cacheable ，當使用ehcache時，autoconfig機制會根據配置文件自動去初始化bean

而shiroConfig在@Configuration構造時，也會去初始化ehcache ,項目啟動會產生如下異常

解決方法：

realm原始代碼(錯誤)：

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) {……}

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

在realm的自動注入下加@Lazy注解，問題解決

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) {……}

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