MyBatis Generator插件如何为？

因为mybatis的tinyint默认映射为bit类型，代码不方便操作和转换。因此需要对类型进行转化 插件地址：（https://github.com/suyin58/mybatis-generator-tddl/blob/master/generator-plugin/src/main/java/com/toolplat/generator/plugins/JavaTypeResolverMybatisDefaultImpl.java） 插件需要继承JavaTypeResolverDefaultImpl，并重写overrideDefaultType方法。针对需要转化的数据类型进行特殊处理 public class JavaTypeResolverMybatisDefaultImpl extends JavaTypeResolverDefaultImpl { @Override protected FullyQualifiedJavaType overrideDefaultType(IntrospectedColumn column, FullyQualifiedJavaType defaultType) { FullyQualifiedJavaType answer = defaultType; switch (column.getJdbcType()) { case Types.BIT: answer = this.calculateBitReplacement(column, defaultType); break; case Types.NUMERIC: case Types.DECIMAL: answer = this.calculateBigDecimalReplacement(column, defaultType); break; case Types.TINYINT: answer = new FullyQualifiedJavaType(Integer.class.getName()); break; default: break; } return answer; } } View Code 配置文件中添加该配置：（https://github.com/suyin58/mybatis-generator-tddl/blob/master/generator-test/src/test/resources/generatorConfigMyBatis3.xml） <!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer true，把JDBC DECIMAL 和 NUMERIC 类型解析为java.math.BigDecimal --> <javaTypeResolver type="com.toolplat.generator.plugins.JavaTypeResolverMybatisDefaultImpl"> <property name="forceBigDecimals" value="true" /> </javaTypeResolver> View Code
