简介：          今天抽空写一下生成器比较重要的环节,如何自定义mybatis生成器的sql xml文件,因为原生出来的格式不好看,命名也不符合我们日常使用习惯,很多冗余的sql节点,下面我直接直入主题演示代码了,还是老规矩使用之前教程延续下来的项目用例1.

         今天抽空写一下生成器比较重要的环节,如何自定义mybatis生成器的sql xml文件,因为原生出来的格式不好看,命名也不符合我们日常使用习惯,很多冗余的sql节点,下面我直接直入主题演示代码了,还是老规矩使用之前教程延续下来的项目用例


1.先看看我们原始生成出来的mapper.xml文件,1.节点间没有空行不符合我们日常格式 2.CRUD方法太累赘,我们其实只需要insert,update,delete,select

      courseNum = #{coursenum,jdbcType=INTEGER},
      hasNum = #{hasnum,jdbcType=INTEGER},
      cancelNum = #{cancelnum,jdbcType=INTEGER},
      courseNumInput = #{coursenuminput,jdbcType=INTEGER},
      orderNum = #{ordernum,jdbcType=INTEGER},
      fav = #{fav,jdbcType=BIGINT},
      vipLevel = #{viplevel,jdbcType=INTEGER},
      cancelReason = #{cancelreason,jdbcType=INTEGER},
      createDate = #{createdate,jdbcType=BIGINT},
      lastModDate = #{lastmoddate,jdbcType=BIGINT},
      formatter = #{formatter,jdbcType=VARCHAR},
      status = #{status,jdbcType=TINYINT}
    where id = #{id,jdbcType=BIGINT}
  </update>
</mapper>

2.根据已知问题,我们先处理一下问题吧,保留insert,update,delete方法作为示例,顺便给他们增加隔行的格式化

先看看XMLMapperGenerator.java这个类的getSqlMapElement()方法,可以看到很多addxxx方法,这里就是拼接sql xml文件的逻辑,我们只保留必须的方法

protected XmlElement getSqlMapElement() {
        FullyQualifiedTable table = introspectedTable.getFullyQualifiedTable();
        progressCallback.startTask(getString(
                "Progress.12", table.toString())); //$NON-NLS-1$
        XmlElement answer = new XmlElement("mapper"); //$NON-NLS-1$
        String namespace = introspectedTable.getMyBatis3SqlMapNamespace();
        answer.addAttribute(new Attribute("namespace", //$NON-NLS-1$
                namespace));

        context.getCommentGenerator().addRootComment(answer);

        addResultMapWithoutBLOBsElement(answer);
        addResultMapWithBLOBsElement(answer);
        addExampleWhereClauseElement(answer);
        addMyBatis3UpdateByExampleWhereClauseElement(answer);
        addBaseColumnListElement(answer);
        addBlobColumnListElement(answer);
        addSelectByExampleWithBLOBsElement(answer);
        addSelectByExampleWithoutBLOBsElement(answer);
        addSelectByPrimaryKeyElement(answer);
        addDeleteByPrimaryKeyElement(answer);
        addDeleteByExampleElement(answer);
        addInsertElement(answer);
        addInsertSelectiveElement(answer);
        addCountByExampleElement(answer);
        addUpdateByExampleSelectiveElement(answer);
        addUpdateByExampleWithBLOBsElement(answer);
        addUpdateByExampleWithoutBLOBsElement(answer);
        addUpdateByPrimaryKeySelectiveElement(answer);
        addUpdateByPrimaryKeyWithBLOBsElement(answer);
        addUpdateByPrimaryKeyWithoutBLOBsElement(answer);
        
        return answer;
    }

修改后的方法 

protected XmlElement getSqlMapElement() {
        FullyQualifiedTable table = introspectedTable.getFullyQualifiedTable();
        progressCallback.startTask(getString(
                "Progress.12", table.toString())); //$NON-NLS-1$
        XmlElement answer = new XmlElement("mapper"); //$NON-NLS-1$
        String namespace = introspectedTable.getMyBatis3SqlMapNamespace();
        answer.addAttribute(new Attribute("namespace", //$NON-NLS-1$
                namespace));

        context.getCommentGenerator().addRootComment(answer);

//        addResultMapWithoutBLOBsElement(answer);
//        addResultMapWithBLOBsElement(answer);
//        addExampleWhereClauseElement(answer);
//        addMyBatis3UpdateByExampleWhereClauseElement(answer);
//        addBaseColumnListElement(answer);
//        addBlobColumnListElement(answer);
//        addSelectByExampleWithBLOBsElement(answer);
//        addSelectByExampleWithoutBLOBsElement(answer);
//        addSelectByPrimaryKeyElement(answer);
//        addDeleteByPrimaryKeyElement(answer);
//        addDeleteByExampleElement(answer);
//        addInsertElement(answer);
//        addInsertSelectiveElement(answer);
//        addCountByExampleElement(answer);
//        addUpdateByExampleSelectiveElement(answer);
//        addUpdateByExampleWithBLOBsElement(answer);
//        addUpdateByExampleWithoutBLOBsElement(answer);
//        addUpdateByPrimaryKeySelectiveElement(answer);
//        addUpdateByPrimaryKeyWithBLOBsElement(answer);
//        addUpdateByPrimaryKeyWithoutBLOBsElement(answer);
        
        addResultMapWithoutBLOBsElement(answer);
        addBaseColumnListElement(answer);
        addInsertSelectiveElement(answer);
        addUpdateByPrimaryKeySelectiveElement(answer);
        addDeleteByPrimaryKeyElement(answer);

        return answer;
    }

3.修改这个方法后,我们运行下生成文件看看效果

4.看到上面的文件后发现已经达到我们一个目的了,把多余的方法给去掉,但是格式不够好看,我们来完成下面一个目标,增加sql节点隔行以及修改sql语句缩进格式

继续看XMLMapperGenerator.java类的initializeAndExecuteGenerator()方法

protected void initializeAndExecuteGenerator(
            AbstractXmlElementGenerator elementGenerator,
            XmlElement parentElement) {
        elementGenerator.setContext(context);
        elementGenerator.setIntrospectedTable(introspectedTable);
        elementGenerator.setProgressCallback(progressCallback);
        elementGenerator.setWarnings(warnings);
        elementGenerator.addElements(parentElement);
    }

修改后的方法 

protected void initializeAndExecuteGenerator(
            AbstractXmlElementGenerator elementGenerator,
            XmlElement parentElement) {
        elementGenerator.setContext(context);
        elementGenerator.setIntrospectedTable(introspectedTable);
        elementGenerator.setProgressCallback(progressCallback);
        elementGenerator.setWarnings(warnings);
        parentElement.addElement(new TextElement("")); // 增加一行空白的隔行
        elementGenerator.addElements(parentElement);
    }


打开OutputUtilities.java方法看

public static void xmlIndent(StringBuilder sb, int indentLevel) {
        for (int i = 0; i < indentLevel; i++) {
            sb.append("  "); //$NON-NLS-1$
        }
    }

把两个空格符变成4个空格符 

public static void xmlIndent(StringBuilder sb, int indentLevel) {
        for (int i = 0; i < indentLevel; i++) {
        	// sb.append("  "); //$NON-NLS-1$
        	sb.append("    "); // 4个空格符
        }
    }


5.修改方法后我们重新生成下xml文件看看效果

6.可以通过上面的修改后文件可以看到已经实现了我们的要求,但是sql id还是不满足我们的要求,应该改成纯粹的insert,update,delete

找到IntrospectedTable.java类的calculateXmlAttributes()方法,可以看到很多的setxxx方法带了具体的字符串参数,这个就是对应sql文件里面的sql id我们把对应的改改

protected void calculateXmlAttributes() {
        setIbatis2SqlMapPackage(calculateSqlMapPackage());
        setIbatis2SqlMapFileName(calculateIbatis2SqlMapFileName());
        setMyBatis3XmlMapperFileName(calculateMyBatis3XmlMapperFileName());
        setMyBatis3XmlMapperPackage(calculateSqlMapPackage());

        setIbatis2SqlMapNamespace(calculateIbatis2SqlMapNamespace());
        setMyBatis3FallbackSqlMapNamespace(calculateMyBatis3FallbackSqlMapNamespace());
        
        setSqlMapFullyQualifiedRuntimeTableName(calculateSqlMapFullyQualifiedRuntimeTableName());
        setSqlMapAliasedFullyQualifiedRuntimeTableName(calculateSqlMapAliasedFullyQualifiedRuntimeTableName());

        setCountByExampleStatementId("countByExample"); //$NON-NLS-1$
        setDeleteByExampleStatementId("deleteByExample"); //$NON-NLS-1$
        setDeleteByPrimaryKeyStatementId("deleteByPrimaryKey"); //$NON-NLS-1$
        setInsertStatementId("insert"); //$NON-NLS-1$
        setInsertSelectiveStatementId("insertSelective"); //$NON-NLS-1$
        setSelectAllStatementId("selectAll"); //$NON-NLS-1$
        setSelectByExampleStatementId("selectByExample"); //$NON-NLS-1$
        setSelectByExampleWithBLOBsStatementId("selectByExampleWithBLOBs"); //$NON-NLS-1$
        setSelectByPrimaryKeyStatementId("selectByPrimaryKey"); //$NON-NLS-1$
        setUpdateByExampleStatementId("updateByExample"); //$NON-NLS-1$
        setUpdateByExampleSelectiveStatementId("updateByExampleSelective"); //$NON-NLS-1$
        setUpdateByExampleWithBLOBsStatementId("updateByExampleWithBLOBs"); //$NON-NLS-1$
        setUpdateByPrimaryKeyStatementId("updateByPrimaryKey"); //$NON-NLS-1$
        setUpdateByPrimaryKeySelectiveStatementId("updateByPrimaryKeySelective"); //$NON-NLS-1$
        setUpdateByPrimaryKeyWithBLOBsStatementId("updateByPrimaryKeyWithBLOBs"); //$NON-NLS-1$
        setBaseResultMapId("BaseResultMap"); //$NON-NLS-1$
        setResultMapWithBLOBsId("ResultMapWithBLOBs"); //$NON-NLS-1$
        setExampleWhereClauseId("Example_Where_Clause"); //$NON-NLS-1$
        setBaseColumnListId("Base_Column_List"); //$NON-NLS-1$
        setBlobColumnListId("Blob_Column_List"); //$NON-NLS-1$
        setMyBatis3UpdateByExampleWhereClauseId("Update_By_Example_Where_Clause"); //$NON-NLS-1$
    }

修改后方法 

protected void calculateXmlAttributes() {
        setIbatis2SqlMapPackage(calculateSqlMapPackage());
        setIbatis2SqlMapFileName(calculateIbatis2SqlMapFileName());
        setMyBatis3XmlMapperFileName(calculateMyBatis3XmlMapperFileName());
        setMyBatis3XmlMapperPackage(calculateSqlMapPackage());

        setIbatis2SqlMapNamespace(calculateIbatis2SqlMapNamespace());
        setMyBatis3FallbackSqlMapNamespace(calculateMyBatis3FallbackSqlMapNamespace());
        
        setSqlMapFullyQualifiedRuntimeTableName(calculateSqlMapFullyQualifiedRuntimeTableName());
        setSqlMapAliasedFullyQualifiedRuntimeTableName(calculateSqlMapAliasedFullyQualifiedRuntimeTableName());

        setCountByExampleStatementId("countByExample"); //$NON-NLS-1$
        setDeleteByExampleStatementId("deleteByExample"); //$NON-NLS-1$
        // setDeleteByPrimaryKeyStatementId("deleteByPrimaryKey"); //$NON-NLS-1$
        setDeleteByPrimaryKeyStatementId("delete"); // deleteByPrimaryKey改成delete
        setInsertStatementId("insert"); //$NON-NLS-1$
        // setInsertSelectiveStatementId("insertSelective"); //$NON-NLS-1$
        setInsertSelectiveStatementId("insert"); // insertSelective改成insert
        setSelectAllStatementId("selectAll"); //$NON-NLS-1$
        setSelectByExampleStatementId("selectByExample"); //$NON-NLS-1$
        setSelectByExampleWithBLOBsStatementId("selectByExampleWithBLOBs"); //$NON-NLS-1$
        setSelectByPrimaryKeyStatementId("selectByPrimaryKey"); //$NON-NLS-1$
        setUpdateByExampleStatementId("updateByExample"); //$NON-NLS-1$
        setUpdateByExampleSelectiveStatementId("updateByExampleSelective"); //$NON-NLS-1$
        setUpdateByExampleWithBLOBsStatementId("updateByExampleWithBLOBs"); //$NON-NLS-1$
        setUpdateByPrimaryKeyStatementId("updateByPrimaryKey"); //$NON-NLS-1$
        // setUpdateByPrimaryKeySelectiveStatementId("updateByPrimaryKeySelective"); //$NON-NLS-1$
        setUpdateByPrimaryKeySelectiveStatementId("update"); // updateByPrimaryKeySelective改成update
        setUpdateByPrimaryKeyWithBLOBsStatementId("updateByPrimaryKeyWithBLOBs"); //$NON-NLS-1$
        setBaseResultMapId("BaseResultMap"); //$NON-NLS-1$
        setResultMapWithBLOBsId("ResultMapWithBLOBs"); //$NON-NLS-1$
        setExampleWhereClauseId("Example_Where_Clause"); //$NON-NLS-1$
        setBaseColumnListId("Base_Column_List"); //$NON-NLS-1$
        setBlobColumnListId("Blob_Column_List"); //$NON-NLS-1$
        setMyBatis3UpdateByExampleWhereClauseId("Update_By_Example_Where_Clause"); //$NON-NLS-1$
    }

7.修改方法后我们再重新生成文件看看效果

8.已经改成比较符合我们规范和使用的xml文件了,看着很让人舒服不别扭;小结:这些修改代码都是源码生成器必经的逻辑,所以有兴趣继续改造的同学可以继续断点查看并按自己的习惯修改,我只是大概讲了那些部分都是关键地方,下一篇我应该会讲解如何增加自定义sql了,大家有兴趣继续学习的请不要错过咯,再次谢谢大家的支持

XML Java 数据格式
使用idea中的Live Templates自定义自动生成Spring所需的XML配置文件格式
本文介绍了在使用Spring框架时，如何通过创建`applicationContext.xml`配置文件来管理对象。首先，在resources目录下新建XML配置文件，并通过IDEA自动生成部分配置。为完善配置，特别是添加AOP支持，可以通过IDEA的Live Templates功能自定义XML模板。具体步骤包括：连续按两次Shift搜索Live Templates，配置模板内容，输入特定前缀（如spring）并按Tab键即可快速生成完整的Spring配置文件。这样可以大大提高开发效率，减少重复工作。
