1.点开datasourse，打开idea带的数据库工具，具体添加数据库连接，这里不描述。

这时点击会生成一个poji

这时生成的pojo中是不带中文注释的，需要自己配置，往下：
3.根据图中的步骤走，找到groovy配置文件

4.根据项目情况，自己定义规则
import com.intellij.database.model.DasTable

import com.intellij.database.util.DasUtil
import java.io.*
import java.text.SimpleDateFormat
import com.intellij.database.model.ObjectKind
/*
* Available context bindings:

* PROJECT project
* FILES files helper

]
FILES.chooseDirectoryAndSave("Choose directory", "Choose where to store generated files") { dir ->
SELECTION.filter { it instanceof DasTable }.each { generate(it, dir) }
}
def generate(table, dir) {
def className = javaName(table.getName(), true)
def fields = calcFields(table)

new File(dir, className + ".java").withPrintWriter("utf-8") { out -> generate(out, className, fields, table) }

}
out.println ""
out.println "}"
}
def isNotEmpty(content) {
return content != null && content.toString().trim().length() > 0
}
def calcFields(table) {
DasUtil.getColumns(table).reduce([]) { fields, col ->
def spec = Case.LOWER.apply(col.getDataType().getSpecification())
def typeStr = typeMapping.find { p, t -> p.matcher(spec).find() }.value
def comm = [
colName : col.getName(),
name : javaName(col.getName(), false),
type : typeStr,
commoent: col.getComment(),

]
if ("id".equals(Case.LOWER.apply(col.getName())))
comm.annos = "\t@TableId(value = \"id\", type = IdType.INPUT)"
fields += [comm]
}
}
def javaName(str, capitalize) {
def s = com.intellij.psi.codeStyle.NameUtil.splitNameIntoWords(str)
.collect { Case.LOWER.apply(it).capitalize() }
.join("")
.replaceAll(/[^\p{javaJavaIdentifierPart}[_]]/, "_")
capitalize || s.length() == 1 ? s : Case.LOWER.apply(s[0]) + s[1..-1]
}
配置好后，重新回到步骤2生成，即可生成想要的带中文的实体啦~
