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
java的dao层接口
-
public
interface WorkerMapper extends Mapper<Worker> {
-
}
xml映射文件
-
<?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">
-
<mapper namespace="com.jjs.kaiwen.dao.WorkerMapper">
-
<resultMap id="BaseResultMap" type="com.jjs.kaiwen.model.Worker">
-
<!--
-
WARNING - @mbggenerated
-
-->
-
<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" />
-
</resultMap>
-
</mapper>
实体对象
-
@Table(name =
"worker")
-
public
class Worker {
-
@Id
-
@GeneratedValue(strategy = GenerationType.IDENTITY)
-
private Integer id;
-
-
@Column(name =
"worker_id")
-
private String workerId;
-
-
private String name;
-
-
@Column(name =
"org_id")
-
private Integer orgId;
-
-
private String status;
-
-
@Column(name =
"role_id")
-
private Integer roleId;
-
-
// getters and setters ...
-
}
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
，也可不加，因为框架提供了默认实现
-
<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<T> {
-
-
/**
-
* 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);
-
//修改返回值类型为实体类型
-
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 {
-
-
// spring 完成属性设置后会调用此方法
-
@Override
-
public
final
void
afterPropertiesSet
()
throws
IllegalArgumentException, BeanInitializationException {
-
// 这里提供了接口供子类去实现
-
checkDaoConfig();
-
-
// Let concrete implementations initialize themselves.
-
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();
-
//通用Mapper
-
if (mapperHelper.isExtendCommonMapper(getObjectType())) {
-
//这里去处理该类所对应的MappedStatement，封装在helper类中处理
-
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<Object>(configuration.getMappedStatements())) {
-
if (
object instanceof MappedStatement) {
-
MappedStatement ms = (MappedStatement)
object;
-
//检查这个MappedStatement是否属于此映射对象
-
if (ms.getId().startsWith(prefix) && isMapperMethod(ms.getId())) {
-
if (ms.getSqlSource() instanceof ProviderSqlSource) {
-
//去设置该statement的sql语句
-
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
{
-
if (this.mapperClass == getMapperClass(ms.getId())) {
-
throw new RuntimeException("请不要配置或扫描通用Mapper接口类：" + this.mapperClass);
-
}
-
Method method = methodMap.get(getMethodName(ms));
-
try
{
-
//第一种，直接操作ms，不需要返回值
-
if (method.getReturnType() == Void.TYPE) {
-
method.invoke(this, ms);
-
}
-
//第二种，返回SqlNode
-
else
if (SqlNode.
class.isAssignableFrom(
method.getReturnType())) {
-
SqlNode sqlNode = (SqlNode) method.invoke(this, ms);
-
DynamicSqlSource dynamicSqlSource = new DynamicSqlSource(ms.getConfiguration(), sqlNode);
-
setSqlSource(ms, dynamicSqlSource);
-
}
-
//第三种，返回
xml
形式的
sql
字符串
-
else
if
(String.class.equals(method.getReturnType()))
{
-
String xmlSql = (String) method.invoke(this, ms);
-
SqlSource sqlSource = createSqlSource(ms, xmlSql);
-
//替换原有的SqlSource
-
setSqlSource(ms, sqlSource);
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
-
<include refid="user_col_sql_id"><property name="alias" value="t1"/>,
-
<include refid="room_col_sql_id"><property name="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
-
<sql id=
"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

/**

-

-

-
public

class CommonServiceImpl<T,PK extends Serializable> implements CommonService<T,PK> {
-
/**

-

-
@Autowired
-
private Mapper<T> 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<T> selectByExample(Example example) {
-
return mapper.selectByExample(example);
-
}
-
}
