hi :
大家好，我目前使用的是spring ehcache作为项目的缓存.详细配置如下:
ehcaceh_config.xml

            />
</ehcache>
@Cacheable(cacheName="userCache")
public ConcurrentMap<Integer, UserModel> getAllUserInfoMap() {
List<UserModel> list = (List<UserModel>) getSqlMapClientTemplate()
.queryForList("user.SELECT_USER_ALL_INFO");
ConcurrentMap<String, UserModel> userMap = null;
if (CollectionUtils.isNotEmpty(list)) {
userMap = new ConcurrentHashMap<String, UserModel>();
for (UserModel userModel : list) {
userMap.put(userModel.getId(), userModel);
}
}
return userMap;
}
@TriggersRemove(cacheName="userCache",removeAll=true)
public void insertUser(UserModel userModel){
getSqlMapClientTemplate().insert("user.INSERT_USER_POJO",  userModel);
}
代码都贴出来了,ehcache的内部机制我不太了解。希望大家指点一下。
现在是这样的场景，先在action 中调用getAllUserInfoMap 方法，ehcache会把所有的数据都放到cache中。
然后在action中调用insertUser方法。如果在insert 方法中不使用@TriggersRemove(cacheName="userCache",removeAll=true)
ehcache不会把新增的数据同步到cache中。但是如果这里把cache remove了以后。下次调用getAllUserInfoMap 方法时候就会重新查询一下数据库。这样就跟我们前期想要的效果不符。实际缓存的意义就不大了。
或许我没把ehcache的原理吃透。所以请大家指点一下。因为项目没有集群所以不考虑用memcached。大家有好的cache方案可以尽情提出来。谢谢大家。
