mybatis-generator扩展教程系列 -- 自定义sql xml文件
来源：互联网 发布：网络歌手唱的歌真难听 编辑：程序博客网 时间：2024/06/14 14:50
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

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

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

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
