springmvc mybatis redis mysql maven搭建基本开发框架 （二）

1：common下面的工作：

a：在common下面的resources下面新建spring和mybatis文件夹，spring是给spring的配置文件使用，mybatis下面给mybatis配置文件使用，mybatis下面新建mapper文件夹。业务的mapper.xml都放在下面。

b：spring文件夹下面新建spring-db.xml文件，内容如下：

spring文件夹下面新建spring-redis.xml文件，内容如下：

<?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:context="http://www.springframework.org/schema/context"

</bean>

<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">

</beans>

spring下面新建文件spring-explain.xml 内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

</context:component-scan>

<context:component-scan base-package="me.explain.caption.cache" />
<import resource="spring-db.xml" />
<import resource="spring-redis.xml" />

</beans>

mybatis文件夹下面新建文件mybatis-configuration.xml，内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">

<setting name="autoMappingBehavior" value="FULL" />
<setting name="defaultExecutorType" value="SIMPLE" />
<setting name="defaultStatementTimeout" value="25000" />
</settings>

</configuration>

c：在common包下面新建文件：

common包下面新建IBaseEntity.java。内容如下：

package me.explain.caption.common;
import java.io.Serializable;
/**
* 继承一下这个类  所有的实体类  不需要写id字段
*
* 编辑时间：2016年4月28日20:23:24
*
* @author 杨中仁
*
*/
public class IBaseEntity implements Serializable{

/**
*
*/
private static final long serialVersionUID = 1L;

private long id; // 编号主键
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}

}

common包下面新建IBaseMapper.java 内容如下：

package me.explain.caption.common;
import org.apache.ibatis.annotations.Options;
/**
* 所有的mapper 继承这个类  如果有get之类的方法  可以直接在xml下面写  不需要从新定义
*
* 编辑时间  2016年4月28日20:59:28
*
*
* @author 杨中仁
*
* @param <T>
*/
public abstract interface IBaseMapper<T extends IBaseEntity>{

public abstract <K extends IBaseEntity> T get(final Long id);

@Options(useGeneratedKeys = true, keyProperty = "id")
public abstract void add(final T target);

public abstract void update(final T target);

public abstract void delete(final Long id);

}

common包下面新建IBaseRedisCache.java文件，内容如下：

文章的字数的限制，不得不放下面的文章，地址：redis缓存的封装类

common包下面新建文件IBaseService.java ，内容如下：

package me.explain.caption.common;
/**
* 使用redis 缓存
*
* 2016年5月2日11:16:56
*
* @author 杨中仁
*
*/
public abstract class IBaseService extends IBaseRedisCache {}

common包下面新建文件RootNamespace.java 内容如下：

package me.explain.caption.common;
/**
* 使用redis主要的key的最上层
*
* 编辑时间：2016年4月28日20:20:13
*
* @author 杨中仁
*
*/
public abstract interface RootNamespace {

public static final String CAPTION_ROOT = "caption";

public static final String CAPTION_SEPARATOR = ":";

}
