</ivy-module>

ivy.xml

1、先引入以上的jar包：

2、使用MongoTemplate：

package com.d.service;

import javax.servlet.http.HttpServletRequest;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.data.mongodb.core.MongoTemplate;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.ResponseBody;

//@RestController

//@RequestMapping("/test")

public class TestService {

    private static final Logger logger = LoggerFactory.getLogger(TestService.class);

     @Autowired

     MongoTemplate mongoTemplate; 

    @RequestMapping(value = "/check", method = RequestMethod.GET)

    @ResponseBody

    public JsonResult<String> check(HttpServletRequest request) {

        try {

            logger.info("Address:{}", request.getLocalAddr());

            logger.info("Name:{}", request.getLocalName());

        } catch (Throwable e) {

            logger.error(e.getMessage());

            logger.debug(e.getMessage(), e);

        }

        return new JsonResult<String>("服务运行正常...").success();

    }

    @RequestMapping(value = "/add", method = RequestMethod.GET)

    @ResponseBody

    public JsonResult<String> add(HttpServletRequest request) {

        try {

            TestMo mo = new TestMo();

            mo.setId("1111");

            mo.setMessage("2222");

            mo.setName("3333");

            mongoTemplate.insert(mo);

        } catch (Throwable e) {

            logger.error(e.getMessage());

            logger.debug(e.getMessage(), e);

            return new JsonResult<String>(e.getMessage()).fail(0);

        }

        return new JsonResult<String>("服务运行正常...").success();

    }

}

3、使用Reosititory:

package com.repository;

import org.springframework.data.mongodb.repository.MongoRepository;

import com.model.MaterialInfo;

public interface MaterialRepository extends MongoRepository<MaterialInfo, String>{

}

Api:

package com.api;

import javax.validation.Valid;

import javax.ws.rs.DELETE;

import javax.ws.rs.GET;

import javax.ws.rs.POST;

import javax.ws.rs.Path;

import javax.ws.rs.QueryParam;

import org.springframework.data.domain.Sort;

import org.springframework.data.mongodb.core.query.Query;

import com.model.MaterialInfo;

import com.utils.QueryResult;

public interface MaterialApi {

    @POST

    @Path("insert")

    MaterialInfo insert(@Valid MaterialInfo materialInfo);

    @DELETE

    @Path("delete")

    void delete(@QueryParam("id") String id);

    @POST

    @Path("update")

    void update(@QueryParam("id") String id);

    @POST

    @Path("save")

    MaterialInfo save(@Valid MaterialInfo materialInfo);

    @GET

    @Path("get")

    MaterialInfo getBroadCastList(String id);

    @POST

    @Path("query/with/paging")

    public QueryResult<MaterialInfo> queryWithPaging(Query query, Sort sort, //

            int start, int limit);

}

Impl:

package com.api.impl;

import javax.ws.rs.Path;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.beans.factory.annotation.Qualifier;

import org.springframework.data.domain.Sort;

import org.springframework.data.mongodb.core.MongoTemplate;

import org.springframework.data.mongodb.core.query.Query;

import org.springframework.stereotype.Component;

import com.api.MaterialApi;

import com.model.MaterialInfo;

import com.repository.MaterialRepository;

import com.utils.QueryResult;

@Path("/material")

@Component("materialImpl")

public class MaterialApiImpl implements MaterialApi {

    @Autowired

    private MaterialRepository _materialRepository;

     @Autowired

     @Qualifier("mongoTemplate")

     MongoTemplate mongoTemplate;

    @Override

    public MaterialInfo insert(MaterialInfo materialInfo) {

        // TODO Auto-generated method stub

        return _materialRepository.insert(materialInfo);

    }

    @Override

    public void delete(String id) {

        // TODO Auto-generated method stub

    }

    @Override

    public MaterialInfo save(MaterialInfo materialInfo) {

        // TODO Auto-generated method stub

        return null;

    }

    @Override

    public MaterialInfo getBroadCastList(String id) {

        // TODO Auto-generated method stub

        return null;

    }

    @Override

    public QueryResult<MaterialInfo> queryWithPaging(Query query, Sort sort, int start, int limit) {

        // TODO Auto-generated method stub

        return null;

    }

    @Override

    public void update(String id) {

        // TODO Auto-generated method stub

    }

}

Service:

package com.service;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Component;

import com.api.MaterialApi;

import com.model.MaterialInfo;

@Component("materialService")

public class MaterialService {

    public static Logger logger = LoggerFactory.getLogger(MaterialService.class);

    @Autowired

    MaterialApi _materialApi;

    public String save(MaterialInfo materialInfo){

        try {

             _materialApi.save(materialInfo);

        } catch (Throwable e) {

            return e.getMessage();

        }

        return "success";

    }

}

以上！

缺少关键的beans.xml文件补上去：注意其中的<mongo:repositories />很重要；

<?xml version="1.0" encoding="UTF-8"?>

    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">

    <!-- 自动扫描 -->

    <context:annotation-config />

    <mvc:annotation-driven />

    <context:component-scan base-package="com.d" />

    <import resource="classpath:com/d/beans.xml"/>    

    <mongo:repositories base-package="com.d.repository"></mongo:repositories>

    <context:property-placeholder location="classpath:com/d/mongodb.properties" />

     <!--

    <mongo:mongo id="mongo"  host="${mongodb.host}" port="${mongodb.port}" />

    -->

     <mongo:mongo id="mongo" replica-set="${mongodb.replicaSet}" />  

    <mongo:db-factory id="mongoDbFactory" dbname="${mongodb.database}"

        mongo-ref="mongo" />  

    <!-- mongo模板操作对象 -->

        <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />

    </bean>  

</beans>

以上文件加载只能加载classpath下的文件，加载外部文件需修改配置如下：
<context:property-placeholder location="file:${app.home}/config/mongodb.properties" />
重点在添加file标识

mongodb.properties：

#mongodb

mongodb.database=adbase

mongodb.replicaSet=127.0.0.1:27017

#mongodb.host=127.0.0.1

#mongodb.port=27017
