本文介绍了如何在IntelliJ IDEA中操作，通过Database窗口连接MySQL数据库，填写数据库信息，创建导出模块，并使用特定模板生成带注释的Bean、DAO和XML文件。详细步骤包括在Database窗口中添加数据库，选中表右键选择相应模板进行文件导出。

1，database窗口

view---Tool windows----databse

2，添加mysql的database

3，填写数据库信息

4，创建导出模块，选中表右键

右键新建Generate MyPOJOs.groovy文件

bean模板代码如下

import com.intellij.database.model.DasTable
import com.intellij.database.util.Case
import com.intellij.database.util.DasUtil
import java.io.*
/*
 * Available context bindings:
 *   SELECTION   Iterable<DasObject>
 *   PROJECT     project
 *   FILES       files helper
 */

packageName = "com.achievement.manager.model.sysconfig;"
typeMapping = [
        (~/(?i)int/)                      : "int",
        (~/(?i)float|double/)             : "java.math.BigDecimal",
        (~/(?i)decimal|real/)             : "java.math.BigDecimal",
        (~/(?i)datetime|timestamp/)       : "java.util.Date",
        (~/(?i)date/)                     : "java.util.Date",
        (~/(?i)time/)                     : "java.util.Date",

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)
    PrintWriter output = new PrintWriter(new OutputStreamWriter(new FileOutputStream( new File(dir, className + ".java")), "utf-8"))
    output.withPrintWriter { out -> generate(out, className, fields) }
}

def generate(out, className, fields) {
    out.println "package $packageName"
    out.println "import java.io.Serializable;"
    out.println ""
    out.println "public class $className implements Serializable{"
    out.println ""
    fields.each() {
        if (isNotEmpty(it.commoent)) {
            out.println ""

            out.println "  /**${it.commoent}**/"
        }
        if (it.annos != "") out.println "  ${it.annos}"
        out.println "  private ${it.type} ${it.name};"
    }
    out.println ""
    fields.each() {
        out.println ""
        out.println "  public ${it.type} get${it.name.capitalize()}() {"
        out.println "    return ${it.name};"
        out.println "  }"
        out.println ""
        out.println "  public void set${it.name.capitalize()}(${it.type} ${it.name}) {"
        out.println "    this.${it.name} = ${it.name};"
        out.println "  }"
        out.println ""
    }
    out.println "}"
