最簡單的SpringMvc+Spring+Mybatis+Mysql+Dubbo案例
1.新建一個maven的web項目，項目結構和pom文件以下：html
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

pom文件引入了SpringMvc+Spring+Mybatis+Dubbo+zookeeeper 這些框架的必要jar，值得注意的是以前一直沒忽略dubbo中的spring的一些jar，致使SpringAop一直報錯only available on JDK 1.5 and higher，緣由是dubbo中的內置spring爲2.5，而我自己用的jdk爲1.8，因此屏蔽掉dubbo中的spring一些jar就能夠了。java
2.web.xml配置，由於是最簡單springmvc，因此web.xml只是用來加載下上下文，web.xml配置文件路徑：src\main\webapp\WEB-INF：mysql
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:jsp="http://java.sun.com/xml/ns/javaee/jsp"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" metadata-complete="false" version="3.1">
<description>TestMock</description>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:applicationContext.xml,classpath*:dubbo-provider.xml</param-value>
</context-param>
</web-app>
3.mybatis配置文件和代碼能夠用MyBatis Generator自動生成便可，mybatis的相關代碼和配置以下：web
3.1 數據庫爲mysql，表名books,表結構以下：spring
3.2 mapping文件BookMapper.xml路徑爲resources下的com\ly\mapping,以下：sql
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!--命名空間應該是對應接口的包名+接口名 -->
<mapper namespace="com.ly.dao.BookDAO">
<!--id應該是接口中的方法，結果類型如沒有配置別名則應該使用全名稱 -->
<!--得到全部圖書 -->
<select id="getAllBooks" resultType="com.ly.model.Book">
select id,title,price,publistDate from books
</select>
<!--得到圖書對象經過編號 -->
<select id="getBookById" resultType="com.ly.model.Book">
select id,title,price,publistDate from books where id=#{id}
</select>
<!-- 增長 -->
<insert id="add">
insert into books(title,price,publistDate)
values(#{title},#{price},#{publistDate})
</insert>
<!-- 刪除 -->
<delete id="delete">
delete from books where id=#{id}
</delete>
<!-- 更新 -->
<update id="update">
update books set title=#{title},price=#{price},publistDate=#{publistDate}
where id=#{id}
</update>
</mapper>
3.3 DAO代碼 BookDAO.java以下：shell
package com.ly.dao;
import java.util.List;
import org.apache.ibatis.annotations.Param;
import com.ly.model.Book;
public interface BookDAO {
/**
* 獲取全部圖書
* @return
*/
public List<Book> getAllBooks();
/**
* 根據id獲取圖書
* @param id
* @return
*/
public Book getBookById(@Param("id")int id);
/**
* 添加圖書
* @param entity
* @return
*/
public int add(Book entity);
/**
* 根據id刪除圖書
* @param id
* @return
*/
public int delete(int id);
/**
* 更新圖書
* @param entity
* @return
*/
public int update(Book entity);
}
3.4 model代碼 Book.java以下：數據庫
package com.ly.model;
import java.util.Date;
public class Book {
private int id;
private String title;
private double price;
private Date publistDate;
public Book(){}
public Book(int id, String title, double price, Date publistDate) {
this.id = id;
this.title = title;
this.price = price;
this.publistDate = publistDate;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
public Date getPublistDate() {
return publistDate;
}
public void setPublistDate(Date publistDate) {
this.publistDate = publistDate;
}
}
3.5 BookServer.java代碼以下：apache
package com.ly.server;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.ly.dao.BookDAO;
import com.ly.model.Book;
@Service
public class BookServer {
@Autowired
private BookDAO bookDAO;
public List<Book> getAllBooks() {
return bookDAO.getAllBooks();
}
public Book getBookById(int id) {
return bookDAO.getBookById(id);
}
}
4. spring配置文件applicationContext.xml 位於 resources下，以下：json
<?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:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.3.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">
<!--1 引入屬性文件，在配置中佔位使用 -->
<context:property-placeholder location="classpath*:stock.properties" />
<!-- 數據源 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
destroy-method="close">
<property name="url" value="${mock.jdbc.url}" />
<property name="driverClassName" value="${mock.jdbc.driver}" />
<property name="username" value="${mock.jdbc.username}" />
<property name="password" value="${mock.jdbc.password}" />
<property name="initialSize" value="${mock.jdbc.initialSize}" />
<property name="minIdle" value="${mock.jdbc.minIdle}" />
<property name="maxWait" value="${mock.jdbc.maxWait}" />
<property name="maxActive" value="${mock.jdbc.maxActive}" />
</bean>
<!--3 會話工廠bean sqlSessionFactoryBean -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 數據源 -->
<property name="dataSource" ref="dataSource"></property>
<!-- sql映射文件路徑 -->
<property name="mapperLocations" value="classpath:com/ly/mapping/*Mapper.xml"></property>
</bean>
<!--4 自動掃描對象關係映射 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!--指定會話工廠，若是當前上下文中只定義了一個則該屬性可省去，多個數據庫啓用 -->
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
<!-- 指定要自動掃描接口的基礎包，實現接口 -->
<property name="basePackage" value="com.ly.dao"></property>
</bean>
<!--5 聲明式事務管理 -->
<!--定義事物管理器，由spring管理事務 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<!--支持註解驅動的事務管理，指定事務管理器 -->
<tx:annotation-driven transaction-manager="transactionManager"/>
<!--6 容器自動掃描IOC組件 -->
<context:component-scan base-package="com.ly"></context:component-scan>
<!--7 aspectj支持自動代理實現AOP功能 -->
<aop:aspectj-autoproxy proxy-target-class="true"></aop:aspectj-autoproxy>
</beans>
其中stock.properties中的數據源配置爲你本身的mysql數據庫，個人以下：
mock.jdbc.url = jdbc:mysql://127.0.0.1:5508/mock?useUnicode=true&characterEncoding=UTF-8
mock.jdbc.driver = com.mysql.jdbc.Driver
mock.jdbc.username = mock
mock.jdbc.password = mock
mock.jdbc.initialSize = 1
mock.jdbc.minIdle = 2
mock.jdbc.maxWait = 5000
mock.jdbc.maxActive = 5
具體的applicationContext.xml含義基本有註釋
5. dubbo的配置和代碼
5.1 dubbo配置文件 dubbo-provider.xml 也位於 resources下，zookeeper本身本地安裝一個，以下：
<?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:dubbo="http://code.alibabatech.com/schema/dubbo"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://code.alibabatech.com/schema/dubbo
http://code.alibabatech.com/schema/dubbo/dubbo.xsd ">
<!--應用名稱-->
<dubbo:application name="TestMockServer" />
<!-- 註冊地址 -->
<dubbo:registry address="zookeeper://127.0.0.1:2181" />
<!-- 接口的位置 -->
<dubbo:service interface="com.ly.server.SayHelloServer"
ref="frameService" executes="10" />
<!-- 實現bean，客戶端應用的bean就以這個id名稱爲主 -->
<bean id="frameService" class="com.ly.server.impl.SayHelloServerImpl" />
</beans>
5.2 dubbo接口代碼 SayHelloServer.java以下：
package com.ly.server;
public interface SayHelloServer {
public String sayHello(String hello);
}
5.2 接口實現代碼SayHelloServerImpl.java 以下：
package com.ly.server.impl;
import com.ly.server.SayHelloServer;
public class SayHelloServerImpl implements SayHelloServer {
public String sayHello(String hello) {
System.out.println("Client: "+ hello);
return hello + " Server: ";
}
}
如今基本上SpringMvc+Spring+Mybatis+Mysql+Dubbo就已經整合完成了，本地下載一個tomcat，把項目打包發佈到tomcat下啓動，就能在dubbo的monitor中發現該項目的SayHelloServer接口已經註冊在zk上面了。
附上個人自動發佈shell腳本，一個很簡單的shell腳本：
#!/bin/sh
#判斷進程存在
tomcatId=0
tomcatID=`ps -ef | grep org.apache.catalina.startup.Bootstrap | grep -v grep | awk '{print $2}'`
echo "MockServer tomcat is " $tomcatID
if [ -n "$tomcatID" ];then
echo 'current tomcat pid is:'$tomcatID
kill -15 $tomcatID && echo "MockServer kill -15"
kill -9 $tomcatID && echo "MockServer kill -9"
else
echo $sysName " not start"
fi
sleep 2
#編譯
cd /Users/ly/Documents/workspace/MockServer
mvn clean install -Dmaven.test.skip=true -U
sleep 5
#部署本地
cd target
rm -rf /Users/ly/tomcat/apache-tomcat-9.0.4/webapps/ROOT/*
unzip -q mock_server.war -d /Users/ly/tomcat/apache-tomcat-9.0.4/webapps/ROOT/
nohup sh /Users/ly/tomcat/apache-tomcat-9.0.4/bin/startup.sh & sleep 3
echo "MockServer is starting......"
