這篇文章主要為大家介紹了mybatis-generator-gui根據(jù)需求改動(dòng)示例,有需要的朋友可以借鑒參考下,希望能夠有所幫助,祝大家多多進(jìn)步,早日升職加薪

JavaType解析類

改的都是自己覺得需要改的部分

在生成的實(shí)體類中，數(shù)據(jù)庫(kù)tinyint類型默認(rèn)會(huì)生成Byte，使用時(shí)略有不便。于是將其改成Integer。

自定義一個(gè)JavaType解析的類

package com.zzg.mybatis.generator.plugins;
public class MyJavaTypeResolverImpl extends JavaTypeResolverDefaultImpl {
    @Override
    protected FullyQualifiedJavaType overrideDefaultType(IntrospectedColumn column, FullyQualifiedJavaType defaultType) {
        FullyQualifiedJavaType answer = defaultType;
        switch (column.getJdbcType()) {
            case Types.TINYINT:
                answer = new FullyQualifiedJavaType(Integer.class.getName());
                break;
            default:
                break;
        }
        return answer;
    }
}

在加載配置的過程中進(jìn)行加載即可（MybatisGeneratorBridge:210）

//for JSR310
        if (generatorConfig.isJsr310Support()) {
            JavaTypeResolverConfiguration javaTypeResolverConfiguration = new JavaTypeResolverConfiguration();
           javaTypeResolverConfiguration.setConfigurationType("com.zzg.mybatis.generator.plugins.JavaTypeResolverJsr310Impl");
            context.setJavaTypeResolverConfiguration(javaTypeResolverConfiguration);
        } else {
            // 《TINYINT的JavaType改為Integer》
            JavaTypeResolverConfiguration myJavaTypeResolverConfiguration = new JavaTypeResolverConfiguration();
           myJavaTypeResolverConfiguration.setConfigurationType("com.zzg.mybatis.generator.plugins.MyJavaTypeResolverImpl");
            context.setJavaTypeResolverConfiguration(myJavaTypeResolverConfiguration);
        }

去掉不必要的默認(rèn)勾選

找到MainUI.fxml；

找到對(duì)應(yīng)的checkbox，把selected修改為false即可。

生成lombok常用注解

自定義lombok插件

package com.zzg.mybatis.generator.plugins;
public class LombokPlugin extends PluginAdapter {
    public LombokPlugin() {
    }
    @Override
    public boolean validate(List<String> list) {
        return true;
    }
    @Override
    public boolean modelBaseRecordClassGenerated(TopLevelClass topLevelClass, IntrospectedTable introspectedTable) {
        topLevelClass.addImportedType("lombok.Data");
        topLevelClass.addAnnotation("@Data");
        topLevelClass.addImportedType("lombok.ToString");
        topLevelClass.addAnnotation("@ToString");
        topLevelClass.addImportedType("lombok.Builder");
        topLevelClass.addAnnotation("@Builder");
        topLevelClass.addImportedType("lombok.NoArgsConstructor");
        topLevelClass.addAnnotation("@NoArgsConstructor");
        topLevelClass.addImportedType("lombok.AllArgsConstructor");
        topLevelClass.addAnnotation("@AllArgsConstructor");
        topLevelClass.addJavaDocLine("/**");
        topLevelClass.addJavaDocLine("* @author 我");
        topLevelClass.addJavaDocLine("* @date " + this.date2Str(new Date()));
        topLevelClass.addJavaDocLine("*/");
        return true;
    }
    @Override
    public boolean clientGenerated(Interface interfaze, TopLevelClass topLevelClass, IntrospectedTable introspectedTable) {
        interfaze.addJavaDocLine("/**");
        interfaze.addJavaDocLine("* @author 我");
        interfaze.addJavaDocLine("* @date " + this.date2Str(new Date()));
        interfaze.addJavaDocLine("*/");
        return true;
    }
    @Override
    public boolean modelSetterMethodGenerated(Method method, TopLevelClass topLevelClass, IntrospectedColumn introspectedColumn, IntrospectedTable introspectedTable, ModelClassType modelClassType) {
        return false;
    }
    @Override
    public boolean modelGetterMethodGenerated(Method method, TopLevelClass topLevelClass, IntrospectedColumn introspectedColumn, IntrospectedTable introspectedTable, ModelClassType modelClassType) {
        return false;
    }
    private String date2Str(Date date) {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd");
        return sdf.format(date);
    }
}

在加載配置的過程中進(jìn)行加載即可（加到MybatisGeneratorBridge:182下面）
