我在最新版本idea使用easycode遇到这个问题，在网上搜了一下，说是版本问题，使用以下办法就可以快速解决：在idea设置里面找到othersettings里的easycode，要替换其中两个模板，分别是 Template 下的 mapper.xml.vm 和 Global Config 下的 mybatisSupport.vm ，可以直接复制模板内容，进行替换即可。
mapper.xml.vm`：
##引入mybatis支持 $!{mybatisSupport.vm} ##设置保存名称与保存位置 $!callback.setFileName($tool.append($!{tableInfo.name}, "Dao.xml")) $!callback.setSavePath($tool.append($modulePath, "/src/main/resources/mapper")) ##拿到主键 #if(!$tableInfo.pkColumn.isEmpty()) #set($pk = $tableInfo.pkColumn.get(0)) #end <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="$!{tableInfo.savePackageName}.dao.$!{tableInfo.name}Dao"> <resultMap type="$!{tableInfo.savePackageName}.entity.$!{tableInfo.name}" id="$!{tableInfo.name}Map"> #foreach($column in $tableInfo.fullColumn) <result property="$!column.name" column="$!column.obj.name" jdbcType="$!column.ext.jdbcType"/> #end </resultMap> <!--查询单个--> <select id="queryById" resultMap="$!{tableInfo.name}Map"> select #allSqlColumn() from $!tableInfo.obj.name where $!pk.obj.name = #{$!pk.name} </select> <!--查询指定行数据--> <select id="queryAllByLimit" resultMap="$!{tableInfo.name}Map"> select #allSqlColumn() from $!tableInfo.obj.name <where> #foreach($column in $tableInfo.fullColumn) <if test="$!column.name != null#if($column.type.equals("java.lang.String")) and $!column.name != ''#end"> and $!column.obj.name = #{$!column.name} </if> #end </where> limit #{pageable.offset}, #{pageable.pageSize} </select> <!--统计总行数--> <select id="count" resultType="java.lang.Long"> select count(1) from $!tableInfo.obj.name <where> #foreach($column in $tableInfo.fullColumn) <if test="$!column.name != null#if($column.type.equals("java.lang.String")) and $!column.name != ''#end"> and $!column.obj.name = #{$!column.name} </if> #end </where> </select> <!--新增所有列--> <insert id="insert" keyProperty="$!pk.name" useGeneratedKeys="true"> insert into $!{tableInfo.obj.name}(#foreach($column in $tableInfo.otherColumn)$!column.obj.name#if($foreach.hasNext), #end#end) values (#foreach($column in $tableInfo.otherColumn)#{$!{column.name}}#if($foreach.hasNext), #end#end) </insert> <insert id="insertBatch" keyProperty="$!pk.name" useGeneratedKeys="true"> insert into $!{tableInfo.obj.name}(#foreach($column in $tableInfo.otherColumn)$!column.obj.name#if($foreach.hasNext), #end#end) values <foreach collection="entities" item="entity" separator=","> (#foreach($column in $tableInfo.otherColumn)#{entity.$!{column.name}}#if($foreach.hasNext), #end#end) </foreach> </insert> <insert id="insertOrUpdateBatch" keyProperty="$!pk.name" useGeneratedKeys="true"> insert into $!{tableInfo.obj.name}(#foreach($column in $tableInfo.otherColumn)$!column.obj.name#if($foreach.hasNext), #end#end) values <foreach collection="entities" item="entity" separator=","> (#foreach($column in $tableInfo.otherColumn)#{entity.$!{column.name}}#if($foreach.hasNext), #end#end) </foreach> on duplicate key update #foreach($column in $tableInfo.otherColumn)$!column.obj.name = values($!column.obj.name)#if($foreach.hasNext), #end#end </insert> <!--通过主键修改数据--> <update id="update"> update $!{tableInfo.obj.name} <set> #foreach($column in $tableInfo.otherColumn) <if test="$!column.name != null#if($column.type.equals("java.lang.String")) and $!column.name != ''#end"> $!column.obj.name = #{$!column.name}, </if> #end </set> where $!pk.obj.name = #{$!pk.name} </update> <!--通过主键删除--> <delete id="deleteById"> delete from $!{tableInfo.obj.name} where $!pk.obj.name = #{$!pk.name} </delete> </mapper>
mybatisSupport.vm：
##针对Mybatis 进行支持，主要用于生成xml文件 #foreach($column in $tableInfo.fullColumn) ##储存列类型 $tool.call($column.ext.put("sqlType", $tool.getField($column.obj.dataType, "typeName"))) #if($tool.newHashSet("java.lang.String").contains($column.type)) #set($jdbcType="VARCHAR") #elseif($tool.newHashSet("java.lang.Boolean", "boolean").contains($column.type)) #set($jdbcType="BOOLEAN") #elseif($tool.newHashSet("java.lang.Byte", "byte").contains($column.type)) #set($jdbcType="BYTE") #elseif($tool.newHashSet("java.lang.Integer", "int", "java.lang.Short", "short").contains($column.type)) #set($jdbcType="INTEGER") #elseif($tool.newHashSet("java.lang.Long", "long").contains($column.type)) #set($jdbcType="INTEGER") #elseif($tool.newHashSet("java.lang.Float", "float", "java.lang.Double", "double").contains($column.type)) #set($jdbcType="NUMERIC") #elseif($tool.newHashSet("java.util.Date", "java.sql.Timestamp", "java.time.Instant", "java.time.LocalDateTime", "java.time.OffsetDateTime", " java.time.ZonedDateTime").contains($column.type)) #set($jdbcType="TIMESTAMP") #elseif($tool.newHashSet("java.sql.Date", "java.time.LocalDate").contains($column.type)) #set($jdbcType="TIMESTAMP") #else ##其他类型 #set($jdbcType="VARCHAR") #end $tool.call($column.ext.put("jdbcType", $jdbcType)) #end ##定义宏，查询所有列 #macro(allSqlColumn)#foreach($column in $tableInfo.fullColumn)$column.obj.name#if($foreach.hasNext), #end#end#end
