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 public ${field.propertyType} ${getprefix}${field.capitalName}() { return ${field.propertyName}; } #if(${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
