ibator1.2.1扩展支持Oracle、MySQL分页

最近在项目中用到ibator1.2.1,但是感觉其自动生成的代码不能满足自己的需要,在网上找了资料:
1. eclipse ibabis代码生成插件abator功能扩展
2. aquan198163 写道 可以用iBatis的include标签设计类似模板的东西,简化分页sql
自己下载代码进行了相关扩展:
1.支持Oracle、MySQL分页
2.在生成的example类增加了Oracle、MySQL分页的相关字段

0.3版本:
增加了控制生成oracle分页和mysql分页的属性(原来是都生成)
	<!-- 
		<table tableName="BROWSELOGS" enableMysqlPagination="true">
		<table tableName="BROWSELOGS" enableOraclePagination="false" >
			 -->
		<table tableName="BROWSELOGS">
			<columnOverride column="ID" javaType="Integer" />
			<columnOverride column="VISITOR" javaType="Integer" />
			<columnOverride column="DOTIME" jdbcType="Timestamp" />
		</table>

当然这个时候,xml会报错,因为你引用的是网络上面的dtd("http://ibatis.apache.org/dtd/ibator-config_1_0.dtd"),不用理会,一样可以生成,如果都不填写,就是都不生成。
建议在ibatorContext加上 Ibatis2Java5
	<classPathEntry location="D:\UserLibraries\Oracle10g_driver.jar" />
	<ibatorContext id="context" targetRuntime="Ibatis2Java5"  >

完整版的配置:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE ibatorConfiguration PUBLIC "-//Apache Software Foundation//DTD Apache iBATIS Ibator Configuration 1.0//EN" "http://ibatis.apache.org/dtd/ibator-config_1_0.dtd" >
<ibatorConfiguration>
	<classPathEntry location="D:\UserLibraries\mysql-connector-java-5.1.12-bin.jar" />
	<ibatorContext id="context1" targetRuntime="Ibatis2Java5">
		<jdbcConnection driverClass="com.mysql.jdbc.Driver"
			connectionURL="jdbc:mysql://localhost:3306/demo" userId="root"
			password="aaa" />
		<javaModelGenerator targetPackage="com.ibatis.pojo"
			targetProject="test" />
		<sqlMapGenerator targetPackage="com.ibatis.sqlmap"
			targetProject="test" />
		<daoGenerator targetPackage="com.ibatis.dao"
			targetProject="test" type="SPRING" />
		<table tableName="ueye_account" enableMysqlPagination="true">
		<columnOverride column="ID" javaType="Integer" />
			<columnOverride column="VISITOR" javaType="Integer" />
			<columnOverride column="DOTIME" jdbcType="Timestamp" />
		</table>
	</ibatorContext>
</ibatorConfiguration>


0.2版本增加了:
4个list的set方法:

protected List criteriaWithoutValue;

        protected List criteriaWithSingleValue;

        protected List criteriaWithListValue;

        protected List criteriaWithBetweenValue;

原来的方法里面没有set。只有get方法,我觉得有时候我不知道传入的是哪个字段,要自己定义一个条件不知道怎么放进去,我就想法先取出list,在set进去,如下:

//		//过滤条件,仿造的是example类中的情况
//		Criteria criteria=example.createCriteria();
//		//得到example里面的list
//		List<Object> listSingle=criteria.getCriteriaWithSingleValue();
//		//再把它注入回去
//		criteria.setCriteriaWithSingleValue(this.processFilterInfo(listSingle, sigma.getFilterInfo()));
processFilterInfo方法:
public List<Object> processFilterInfo(List<Object> listSingle,List<FilterInfo> filterInfos){
		for (int i = 0; i < filterInfos.size(); i++) {
			String columnId=filterInfos.get(i).getColumnId();
			String logic=filterInfos.get(i).getLogic();
			String value=filterInfos.get(i).getValue();
			if(logic.equalsIgnoreCase("equal")){
				Map<String,Object> map = new HashMap<String,Object>();
	            map.put("condition", columnId+" =");
	            map.put("value", value);
	            listSingle.add(map);
			}else if(logic.equalsIgnoreCase("notequal")){
				Map<String,Object> map = new HashMap<String,Object>();
				map.put("condition", columnId+" <>");
				map.put("value", value);
				listSingle.add(map);

SQL_MAP.xml部分:

  <select id="ibatorgenerated_selectByExample" resultMap="ibatorgenerated_BaseResultMap" parameterClass="com.ibatis.pojo.GoodsExample" >
    <!-- 增加oracle分页头部 -->

    select id, name, stand, money, leavings, orders
    from goods
    <isParameterPresent >

    <!-- 增加oracle分页尾部 -->
    <include refid="oracle_Pagination_Tail" />
    <!-- 增加MySQL分页 -->

Example类部分:
public class GoodsExample {
    protected String orderByClause;

    private Integer oracleStart;

    private Integer oracleEnd;

    private Integer mysqlOffset;

    private Integer mysqlLength;

    protected List oredCriteria;

    public GoodsExample() {
        oredCriteria = new ArrayList();
    }
}
