MongDB之各种修改操作

接口IMongDaoUpdate：

package com.net.test.mongdb.dao;

import com.net.test.mongdb.entity.User;

public interface IMongDaoUpdate {

    public void updateUser(User user);

    public void updateUserHobby(User user);

    public void updateUserHobbyDiffer(User user);

    public void updateUserUserPsg(User user);

    public void deleteUserUserPsg(String name,String field);
}

实现类：

package com.net.test.mongdb.dao.imp;

import javax.annotation.Resource;

import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.query.Criteria;
import org.springframework.data.mongodb.core.query.Query;
import org.springframework.data.mongodb.core.query.Update;
import org.springframework.stereotype.Repository;

import com.net.test.mongdb.dao.IMongDaoUpdate;
import com.net.test.mongdb.entity.User;
