开发框架整合与搭建：spring boot+mybatis+jedis

项目使用maven进行开发

1.pom.xml文件添加依赖

<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<java.version>1.8</java.version>
	</properties>
	<parent>
		<groupId>org.springframework.boot</groupId>

		<version>1.2.5.RELEASE</version>
	</parent>
	<dependencies>
		<dependency>
			<groupId>junit</groupId>
			<artifactId>junit</artifactId>
			<version>4.7</version>
			<scope>test</scope>
		</dependency>
		<dependency>

	</dependencies>
<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>


	<repositories>
		<repository>

	</pluginRepositories>

2.在src/main/resource目录下新建配置文件application.properties（配置信息）

spring.datasource.url=jdbc:mysql://localhost:3306/eshop
spring.datasource.username=root
spring.datasource.password=88888
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

3.在src/main/resource目录下新建文件夹templates（springboot没有这文件夹会报错的）和mybatis文件夹（项目如果使用mybatis的话，用来放置xml文件）

4.写一个springboot入口类，如下：

package com.kang.eshop.product.ha;

import java.util.HashSet;
import java.util.Set;

import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.tomcat.jdbc.pool.DataSource;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.embedded.ServletListenerRegistrationBean;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.PlatformTransactionManager;

import com.kang.eshop.product.ha.listener.InitListener;

import redis.clients.jedis.HostAndPort;
import redis.clients.jedis.JedisCluster;



/**
 * 库存服务Application入口类
 * @author kangkang
 *
 */

@EnableAutoConfiguration
@SpringBootApplication
@ComponentScan
@MapperScan("com.kang.eshop.product.ha.mapper")
public class Application {


	/**
	 * 构建数据源
	 * @return DataSource
	 */
	@Bean
	@ConfigurationProperties(prefix="spring.datasource")
	public DataSource dataSource(){
		return new DataSource();
	}

	/**
	 * 构建mybatis入口类
	 * @return SqlSessionFactory
	 * @throws Exception
	 */
	@Bean
	public SqlSessionFactory sqlSessionFactoryBean() throws Exception {
		SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
		sqlSessionFactoryBean.setDataSource(dataSource());
		PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
		sqlSessionFactoryBean.setMapperLocations(resolver.getResources("classpath:/mybatis/*.xml"));
		return sqlSessionFactoryBean.getObject();
	}

	/**
	 * 构建事务管理器
	 * @return PlatformTransactionManager
	 */
	public PlatformTransactionManager transactionManager(){
		return new DataSourceTransactionManager(dataSource());
	}
	
	/**
	 * redis cluster管理器
	 * @return JedisCluster
	 */
//	@Bean
//	public JedisCluster JedisClusterFactory() {
//		Set<HostAndPort> jedisClusterNodes = new HashSet<HostAndPort>();
//		jedisClusterNodes.add(new HostAndPort("139.199.10.125", 6379));
//		jedisClusterNodes.add(new HostAndPort("139.199.10.125", 7001));
//		jedisClusterNodes.add(new HostAndPort("139.199.10.125", 7002));
//		JedisCluster jedisCluster = new JedisCluster(jedisClusterNodes);
//		return jedisCluster;
//	}

    /**
     * 注册监听器
     * rawtypes大概是说传参时，不该传递基本的类型，导致参数过长，应该传递一个对象把这些参数包装起来
     * @return
     */
	@SuppressWarnings({"rawtypes","unchecked"})
	@Bean
	public ServletListenerRegistrationBean servletListenerRegistrationBean(){
		ServletListenerRegistrationBean servletListenerRegistrationBean=
				new ServletListenerRegistrationBean();
		servletListenerRegistrationBean.setListener(new InitListener());
		return servletListenerRegistrationBean;
		
	} 
	
	/**
	 * Spring Boot Application 启动入口方法
	 * 
	 */
	public static void main( String[] args ){
		SpringApplication.run(Application.class, args);
	}
}

5.新建各种包,注意，Application类放在最外层

6.测试springboot是否搭建成功

package com.kang.eshop.product.ha.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;


/**
 * 测试Controller控制器
 * @author Administrator
 *
 */
@Controller
public class HelloController {
	
	@RequestMapping("/hello")
	@ResponseBody
	public String getUserInfo(String name) {
		return "hello! "+name;
	}
}

浏览器访问：http://localhost:8080/hello?name=tom

如果后台接受成功，则搭建成功！
