tkmybatis是在mybatis框架的基础上提供了很多工具，让开发更加高效，下面来看看这个框架的基本使用，后面会对相关源码进行分析，感兴趣的同学可以看一下，挺不错的一个工具
实现对员工表的增删改查的代码
public interface WorkerMapper extends Mapper <Worker > { xml映射文件
<mapper namespace ="com.jjs.kaiwen.dao.WorkerMapper" >
<resultMap id ="BaseResultMap" type ="com.jjs.kaiwen.model.Worker" >
<id column ="id" jdbcType ="INTEGER" property ="id" />
<result column ="worker_id" jdbcType ="VARCHAR" property ="workerId" />
<result column ="name" jdbcType ="VARCHAR" property ="name" />
<result column ="org_id" jdbcType ="INTEGER" property ="orgId" />
<result column ="status" jdbcType ="VARCHAR" property ="status" />
<result column ="role_id" property ="roleId" jdbcType ="INTEGER" />

public class Worker {@Id
@GeneratedValue (strategy = GenerationType.IDENTITY)
private Integer id;
@Column (name = "worker_id" )

以上就是实现对Worker进行增删改查的所有代码，包括选择性更新、插入、删除等，所有的方法列表如下
以后对表字段的添加或修改只需要更改实体对象的注解，不需要修改xml映射文件，如将worker_id改成worker_no
@Column (name = "worker_no" )
private String workerNo; 数据源的配置，只需要将org.mybatis.spring.mapper.MapperScannerConfigurer改成tk.mybatis.spring.mapper.MapperScannerConfigurer，然后加一个属性
<bean class ="tk.mybatis.spring.mapper.MapperScannerConfigurer" >
<property name ="sqlSessionFactoryBeanName" value ="sqlSessionFactory" />
<property name ="basePackage" value ="com.jjs.zanbi.dao" />
<property name ="properties" >
<value >
mappers=tk.mybatis.mapper.common.Mapper
value >
property >
bean >
用这个库之后写代码感觉在飞…….如果只是简单的了解此框架到这里就可以了，下面是对框架实现原理的分析
原理的简单分析
此框架为我们实现这些功能所有的改动都在Mapper层面，所有的Mapper都继承了tk.mybatis.mapper.common.Mapper
public interface WorkerMapper extends Mapper <Worker > { Mapper接口的声明如下，可以看到Mapper接口实现了所有常用的方法
public interface Mapper <T > extends
BaseMapper <T >,
ExampleMapper <T >,
RowBoundsMapper <T >,
Marker { 看一下完整的UML图，太大了，可以用新窗口打开，放大之后再看
这里选择一个接口：SelectOneMapper接口，对于源码进行简单分析，此接口声明如下：
public interface SelectOneMapper {
/**
* 根据实体中的属性进行查询，只能有一个返回值，有多个结果是抛出异常，查询条件使用等号
*
* @param record
* @return
*/
@SelectProvider (type = BaseSelectProvider.class , method = "dynamicSQL" )
T selectOne(T record);
}

@SelectProvider是mybatis3之后提供的，用于灵活的设置sql来源，这里设置了服务提供类和方法，但这个库并没有直接用method指定的方法来返回sql，而是在运行时进行解析的，代码如下
public class BaseSelectProvider extends MapperTemplate {public String selectOne (MappedStatement ms) {
Class entityClass = getEntityClass(ms);
setResultType(ms, entityClass);
StringBuilder sql = new StringBuilder();
sql.append(SqlHelper.selectAllColumns(entityClass));
sql.append(SqlHelper.fromTable(entityClass, tableName(entityClass)));
sql.append(SqlHelper.whereAllIfColumns(entityClass, isNotEmpty()));
return sql.toString();
}
}

到这里我们就大概知道了这个库为我们提供便利的原理了，总的来说就是这个库帮我们提供了对表的基本操作的sql，帮我们省了很多工作量，而且维护起来也很方便，否则我们的xml文件动不动就几百行甚至上千行
对源码的探索不能到这里停止，最起码要分析到与另一个框架的整合点
我们知道，mybatis的mapper接口是在启动的时候被框架以JdkProxy的形式封装了的，具体对应的类是MapperFactoryBean，这个类中有一个checkDaoConfig()方法，是从父类继承并重写了该方法，继承结构如下
MapperFactoryBean -> SqlSessionDaoSupport -> DaoSupport 这里的DaoSupport就是spring提供的Dao的抽象，代码如下
public abstract class DaoSupport implements InitializingBean {@Override
public final void afterPropertiesSet () throws IllegalArgumentException, BeanInitializationException {
checkDaoConfig();
try {
initDao();
}
catch (Exception ex) {
throw new BeanInitializationException("Initialization of DAO failed" , ex);
}
}
protected abstract void checkDaoConfig () throws IllegalArgumentException;
protected void initDao () throws Exception {
}
}

框架自定义的MapperFactoryBean重写了checkDaoConfig()方法，完成对所有sql语句的设置，代码如下
@Override
protected void checkDaoConfig () {
super .checkDaoConfig();
if (mapperHelper.isExtendCommonMapper(getObjectType())) {
mapperHelper.processConfiguration(getSqlSession().getConfiguration(), getObjectType());
}
}
MapperHelper的processConfiguration方法如下
public void processConfiguration (Configuration configuration, Class mapperInterface) {
String prefix;
if (mapperInterface != null ) {
prefix = mapperInterface.getCanonicalName();
} else {
prefix = "" ;
}
for (Object object : new ArrayList(configuration.getMappedStatements())) {
if (object instanceof MappedStatement) {
MappedStatement ms = (MappedStatement) object ;
if (ms.getId().startsWith(prefix) && isMapperMethod(ms.getId())) {
if (ms.getSqlSource() instanceof ProviderSqlSource) {
setSqlSource(ms);
}
}
}
}
}

设置sql的逻辑，提供了几种不同类型的sqlsource
public void setSqlSource(MappedStatement ms) throws Exception
Method method = methodMap .get (getMethodName(ms) );try
else if (SqlNode.class .isAssignableFrom(method .getReturnType () ))
//第三种，返回xml 形式的sql 字符串
else if (String.class .equals (method .getReturnType() ))

到这里整个sql的获取流程就分析完了，本人用这个库写过一个小项目，确实节省了开发的工作量，而且DAO层的结构更加清晰简洁了
关于mybatis新特性
从3.4.0开始，mybatis提供对外部表的alias引用方法，多表联合查询就方便多了，我们先看原始的方式是怎样做的
select a.id,a.name,b.bid,b.bname .....
from user a
left join room b 原始的方式是将所有的表字段列出来，再来看用新特性怎样做
select id="selectUsers" resultType="map" >
select
"user_col_sql_id" "alias" value ="t1" />,
"room_col_sql_id">"alias" value ="t2" />
from user t1
left join room t2
select> 这里主要就是对基本的sql进行了复用，如果对表进行了修改只要在原始的sql节点修改就可以了，就算是5个表的联合查询，sql也是清晰易懂，维护起来会更轻松
新版本的mybatis对于对象映射也提供了更友好的方式，直接使用外部的ResultMap再加上查询语句中的别名就映射完成了
<resultMap id ="workerResultMap" type ="com.jjs.kaiwen.model.Worker" extends ="BaseResultMap" >
<association property ="room" columnPrefix ="b_" resultMap ="com.jjs.kaiwen.dao.OrgMapper.BaseResultMap" />
resultMap >
更进一步
敏锐的程序员可能会提出问题，如当多表查询的时候可能会存在字段名称相同的情况，这里的解决方案是给include添加另一个属性
<include refid ="user_col_sql_id_with_alias" >
<property name ="alias" value ="t" />
<property name ="prefix" value ="t_" />
include > 包含prefix的sqlNode如下
"base_column_with_alias">
${ alias }.ID as ${ prefix}ID ,
${ alias }.WORKER_ID as ${ prefix}WORKER_ID ,
${ alias }.NAME as ${ prefix}NAME ,
${ alias }.ZB_ROLE_ID as ${ prefix}ZB_ROLE_ID ,
${ alias }.ORG_ID as ${ prefix}ORG_ID ,
${ alias }.STATUS as ${ prefix}STATUS
</sql>
如果说觉得手动写包含alias和prefix的字段麻烦，可以用，mybatis代码生成器的插件的方式实现，我自己写了一个生成器的插件，可以代码再这里，仅供参考
通用Service类
@Service
public abstract class CommonServiceImpl <T ,PK extends Serializable > implements CommonService <T ,PK > {private Mapper mapper;
public T selectByPrimaryKey(PK entityId) {
return mapper.selectByPrimaryKey(entityId);
}
public int deleteByPrimaryKey(PK entityId) {
return mapper.deleteByPrimaryKey(entityId);
}
public int insert(T record) {
return mapper.insert(record);
}
public int insertSelective(T record) {
return mapper.insertSelective(record);
}
public int updateByPrimaryKeySelective(T record) {
return mapper.updateByPrimaryKeySelective(record);
}
public int updateByPrimaryKey(T record) {
return mapper.updateByPrimaryKey(record);
}
public List selectByExample(Example example) {
return mapper.selectByExample(example);
}
}
