MongoDB在spring中xml傳統配置

背景

舊項目中依然在使用springmvc的xml傳統配置，最近須要使用MongoDB，須要在spring引入MongoDB的鏈接配置。

解決

配置mongodb數據庫

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xmlns:context="http://www.springframework.org/schema/context"
          xmlns:mongo="http://www.springframework.org/schema/data/mongo"
          xsi:schemaLocation=
          "http://www.springframework.org/schema/context
          http://www.springframework.org/schema/context/spring-context-3.0.xsd
          http://www.springframework.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd
          http://www.springframework.org/schema/beans
          http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

    <!-- Default bean name is 'mongo' -->
    <mongo:mongo-client id="mongoClient" host="localhost" port="27017"/>

</beans>

配置mongodb數據工廠

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

配置mongodb的Template

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

配置mongodb的dao文件夾位置

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

mongodb的dao實現

package com.xxx.dao;

import com.xxx.model.Form;
import org.springframework.data.mongodb.repository.MongoRepository;

import java.util.List;

public interface FormRepository extends MongoRepository<Form, String>{

public List<Form> findByCreator(String creator);
}

mongodb的service實現

package com.xxx.service;

import com.xxx.dao.FormRepository;
import com.xxx.model.Form;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service(value = "formService")
public class FormService {

	@Autowired
	FormRepository formRepository;

	/**
	 * 根據建立者，獲取表單
	 * @param creator 建立者
	 * @return 表單列表
	 */
	public List<Form> findByCreator(String creator){
		return formRepository.findByCreator(creator);
	}
}

感覺

若是使用spring boot的配置文件配置的這個方式，是最好的。能不用xml配置就不用，畢竟官方首先教咱們都是去xml化配置的。
