背景

旧项目中依然在使用springmvc的xml传统配置，最近需要使用MongoDB，需要在spring引入MongoDB的连接配置。

解决

配置mongodb数据库

1<?xml version="1.0" encoding="UTF-8"?>
2<beans xmlns="http://www.springframework.org/schema/beans"
3          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4          xmlns:context="http://www.springframework.org/schema/context"
5          xmlns:mongo="http://www.springframework.org/schema/data/mongo"
6          xsi:schemaLocation=
7          "http://www.springframework.org/schema/context
8          http://www.springframework.org/schema/context/spring-context-3.0.xsd
9          http://www.springframework.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd
10          http://www.springframework.org/schema/beans
11          http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
12
13    <!-- Default bean name is 'mongo' -->
14    <mongo:mongo-client id="mongoClient" host="localhost" port="27017"/>
15
16</beans>

配置mongodb数据工厂

<mongo:db-factory id="mongoDbFactory" mongo-ref="mongoClient"/>

配置mongodb的Template

1<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
2	<constructor-arg ref="mongoDbFactory"/>
3</bean>

配置mongodb的dao文件夹位置

<mongo:repositories base-package="com.xxx.dao" mongo-template-ref="mongoTemplate" />

mongodb的dao实现

1package com.xxx.dao;
2
3import com.xxx.model.Form;
4import org.springframework.data.mongodb.repository.MongoRepository;
5
6import java.util.List;
7
8public interface FormRepository extends MongoRepository<Form, String>{
9
10public List<Form> findByCreator(String creator);
11}

mongodb的service实现

1package com.xxx.service;
2
3import com.xxx.dao.FormRepository;
4import com.xxx.model.Form;
5import org.springframework.beans.factory.annotation.Autowired;
6import org.springframework.stereotype.Service;
7
8import java.util.List;
9
10@Service(value = "formService")
11public class FormService {
12
13	@Autowired
14	FormRepository formRepository;
15
16	/**
17	 * 根据创建者，获取表单
18	 * @param creator 创建者
19	 * @return 表单列表
20	 */
21	public List<Form> findByCreator(String creator){
22		return formRepository.findByCreator(creator);
23	}
24}

感受

如果使用spring boot的配置文件配置的这个方式，是最好的。能不用xml配置就不用，毕竟官方首先教我们都是去xml化配置的。
