MyBatis-Plus代码生成器官方默认模板(vm)

 

模板引擎是 velocity(默认引擎)

自己可根据需要稍作修改,如果要大改则需要去看模板引擎的语法了。

1、entity.java.vm

package ${package.Entity};

#foreach($pkg in ${table.importPackages})
import ${pkg};
#end
#
if(${swagger2})
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
#end
#
if(${entityLombokModel})
import lombok.Data;
import lombok.EqualsAndHashCode;
#
if(${chainModel})
import lombok.experimental.Accessors;
#end
#end

/**

  • <p>
  • $!{table.comment}
  • </p>
  • @author ${author}
  • @since ${date}
    */
    #
    if(${entityLombokModel})
    @Data
    #
    if(${superEntityClass})
    @EqualsAndHashCode(callSuper
    = true)
    #
    else
    @EqualsAndHashCode(callSuper
    = false)
    #end
    #
    if(${chainModel})
    @Accessors(chain
    = true)
    #end
    #end
    #
    if(${table.convert})
    @TableName(
    "${table.name}")
    #end
    #
    if(${swagger2})
    @ApiModel(value
    ="${entity} 对象", description="$!{table.comment}")
    #end
    #
    if(${superEntityClass})
    public class ${entity} extends ${superEntityClass}#if(${activeRecord})<${entity}>#end {
    #elseif(${activeRecord})
    public class ${entity} extends Model<${entity}> {
    #
    else
    public class ${entity} implements Serializable {
    #end

#if(${entitySerialVersionUID})
private static final long serialVersionUID=1L;
#end

---------- BEGIN 字段循环遍历 ----------

#foreach($field in ${table.fields})

#if(${field.keyFlag})
#set($keyPropertyName
=${field.propertyName})
#end
#
if("$!field.comment" != "")
#
if(${swagger2})
@ApiModelProperty(value
= "${field.comment}")
#
else
/**
* ${field.comment}
*/
#end
#end
#
if(${field.keyFlag})

主键

#if(${field.keyIdentityFlag})
@TableId(value
= "${field.annotationColumnName}", type = IdType.AUTO)
#elseif(
!$null.isNull(${idType}) && "$!idType" != "")
@TableId(value
= "${field.annotationColumnName}", type = IdType.${idType})
#elseif(${field.convert})
@TableId(
"${field.annotationColumnName}")
#end

普通字段

#elseif(${field.fill})

----- 存在字段填充设置 -----

#if(${field.convert})
@TableField(value
= "${field.annotationColumnName}", fill = FieldFill.${field.fill})
#
else
@TableField(fill
= FieldFill.${field.fill})
#end
#elseif(${field.convert})
@TableField(
"${field.annotationColumnName}")
#end

乐观锁注解

#if(${versionFieldName}==${field.name})
@Version
#end

逻辑删除注解

#if(${logicDeleteFieldName}==${field.name})
@TableLogic
#end
private ${field.propertyType} ${field.propertyName};
#end

---------- END 字段循环遍历 ----------

#if(!${entityLombokModel})
#foreach($field in ${table.fields})
#
if(${field.propertyType.equals("boolean")})
#set($getprefix
="is")
#
else
#set($getprefix
="get")
#end

</span><span style="color: rgba(0, 0, 255, 1)">public</span><span style="color: rgba(0, 0, 0, 1)"> ${field.propertyType} ${getprefix}${field.capitalName}() {
    </span><span style="color: rgba(0, 0, 255, 1)">return</span><span style="color: rgba(0, 0, 0, 1)"> ${field.propertyName};
}

#if(${chainModel})
public ${entity} set${field.capitalName}(${field.propertyType} ${field.propertyName}) {
#
else
public void set${field.capitalName}(${field.propertyType} ${field.propertyName}) {
#end
this.${field.propertyName} = ${field.propertyName};
#
if(${chainModel})
return this;
#end
}
#end

--foreach end---

#end

--end of #if(!${entityLombokModel})--

#if(${entityColumnConstant})
#foreach($field in ${table.fields})
public static final String ${field.name.toUpperCase()} = "${field.name}";

#end
#end
#if(${activeRecord})
@Override
protected Serializable pkVal() {
#
if(${keyPropertyName})
return this.${keyPropertyName};
#
else
return null;
#end
}

#end
#if(!${entityLombokModel})
@Override
public String toString() {
return "${entity}{" +
#foreach($field in ${table.fields})
#
if($!{foreach.index}==0)
"${field.propertyName}=" + ${field.propertyName} +
#
else
", ${field.propertyName}=" + ${field.propertyName} +
#end
#end
"}";
}
#end
}

 

2、controller.java.vm

package ${package.Controller};

import org.springframework.web.bind.annotation.RequestMapping;

#if(${restControllerStyle})
import org.springframework.web.bind.annotation.RestController;
#
else
import org.springframework.stereotype.Controller;
#end
#
if(${superControllerClassPackage})
import ${superControllerClassPackage};
#end

/**

  • <p>
  • $!{table.comment} 前端控制器
  • </p>
  • @author ${author}
  • @since ${date}
    */
    #
    if(${restControllerStyle})
    @RestController
    #
    else
    @Controller
    #end
    @RequestMapping(
    "#if(${package.ModuleName})/${package.ModuleName}#end/#if(${controllerMappingHyphenStyle})${controllerMappingHyphen}#else${table.entityPath}#end")
    #
    if(${kotlin})
    class ${table.controllerName}#if(${superControllerClass}) : ${superControllerClass}()#end

#else
#
if(${superControllerClass})
public class ${table.controllerName} extends ${superControllerClass} {
#
else
public class ${table.controllerName} {
#end

}

#end

 

3、service.java.vm

package ${package.Service};

import ${package.Entity}.${entity};
import ${superServiceClassPackage};

/**

  • <p>
  • $!{table.comment} 服务类
  • </p>
  • @author ${author}
  • @since ${date}
    */
    #
    if(${kotlin})
    interface ${table.serviceName} : ${superServiceClass}<${entity}>
    #
    else
    public interface ${table.serviceName} extends ${superServiceClass}<${entity}> {

}
#end

 

4、serviceImpl.java.vm

package ${package.ServiceImpl};

import ${package.Entity}.${entity};
import ${package.Mapper}.${table.mapperName};
import ${package.Service}.${table.serviceName};
import ${superServiceImplClassPackage};
import org.springframework.stereotype.Service;

/**

  • <p>
  • $!{table.comment} 服务实现类
  • </p>
  • @author ${author}
  • @since ${date}
    */
    @Service
    #
    if(${kotlin})
    open
    class ${table.serviceImplName} : ${superServiceImplClass}<${table.mapperName}, ${entity}>(), ${table.serviceName} {

}
#else
public class ${table.serviceImplName} extends ${superServiceImplClass}<${table.mapperName}, ${entity}> implements ${table.serviceName} {

}
#end

 

5、mapper.java.vm

package ${package.Mapper};

import ${package.Entity}.${entity};
import ${superMapperClassPackage};

/**

  • <p>
  • $!{table.comment} Mapper 接口
  • </p>
  • @author ${author}
  • @since ${date}
    */
    #
    if(${kotlin})
    interface ${table.mapperName} : ${superMapperClass}<${entity}>
    #
    else
    public interface ${table.mapperName} extends ${superMapperClass}<${entity}> {

}
#end

 

6、mapper.xml.vm

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="${package.Mapper}.${table.mapperName}">

#if(${enableCache})
<!-- 开启二级缓存 -->
<cache type="org.mybatis.caches.ehcache.LoggingEhcache"/>

#end
#if(${baseResultMap})
<!-- 通用查询映射结果 -->
<resultMap id="BaseResultMap" type="${package.Entity}.${entity}">
#foreach($field in ${table.fields})
#if(${field.keyFlag})## 生成主键排在第一位
<id column="${field.name}" property="${field.propertyName}" />
#end
#end
#foreach($field in ${table.commonFields})## 生成公共字段
<result column="${field.name}" property="${field.propertyName}" />
#end
#foreach($field in ${table.fields})
#if(!${field.keyFlag})## 生成普通字段
<result column="${field.name}" property="${field.propertyName}" />
#end
#end
</resultMap>

#end
#if(${baseColumnList})
<!-- 通用查询结果列 -->
<sql id="Base_Column_List">
#foreach($field in ${table.commonFields})
${field.columnName},
#end
${table.fieldNames}
</sql>

#end
</mapper>

 

关于默认模板引擎,官方文档说默认使用的是 velocity,引用的依赖也是 velocity,但在示例的代码生成器 CodeGenerator 代码中使用了 freemarker 的模板,需要把此行注掉,使用 velocity

自用 CodeGenerator,在官方示例上稍作修改,增加了部分自己的设置
