前言
公司在做一些基础的功能 不需要重复去操作 比如说单表的增删改查业务代码从controller->service->dao层的相关代码都可以不用程序员去手动编写每一行代码，能更好的利用工具很好的生成。
一：引入依赖
xml
<!-- 添加freemarker依赖 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>二：案例展示
java
private void createSource(CodeCreate codeCreate) {
CodePrj cp = codePrjService.get(codeCreate.getCode());
PrjDs ds = prjDsService.get(cp.getPrjId(), codeCreate.getDsCode());
DbDs dbDs = DbDsUtil.getDbds(ds, codeCreate.getDbName());
List<String> tableList = FrameStringUtil.toArray(codeCreate.getTables(), ",");
List<CodeTemplate> cts = codeTemplateService.findByCode(codeCreate.getCode());
String createPathDir = EnvUtil.get(Env.CODE_SOURCE_PATH);
String dateString = FrameTimeUtil.parseString(FrameTimeUtil.getTime(), FrameTimeUtil.FMT_YYYYMMDDHHMMSS);
String createPath = File.separator + codeCreate.getCode() + File.separator + dateString;
for (String tableName : tableList) {
Table table = dbDs.getTable(tableName);
for (CodeTemplate template : cts) {
String suffix = "." + CodeTemplateType.getText(template.getType());
String curCreatePath = createPath + File.separator;
if(CodeTemplateType.JAVA.getCode() == template.getType().intValue() ||
CodeTemplateType.XML.getCode() == template.getType().intValue()) {
String pk = codeCreate.getPackagePath() + "." + template.getPackageName();
String fileSuffix = template.getSuffix();
curCreatePath += "src" + File.separator + CodeFileUtil.getFolder(pk) + File.separator + table.getClassName() + FrameStringUtil.setFirstCharUpcase(fileSuffix) + suffix;
} else {
curCreatePath += "webapp" + File.separator + table.getBeanName() + "-" + template.getPackageName() + suffix;
}
CodeFileUtil.process(getDescMap(table, codeCreate.getPackagePath()), EnvUtil.get(Env.CODE_TEMPLATE_PATH) + template.getPath(), createPathDir + curCreatePath);
}
}
dbDs.close();
//修改为生成完成 生成zip
String download = createPath + ".zip";
String sourcePath = createPathDir + createPath;
String zipPath = createPathDir + File.separator + codeCreate.getCode() + File.separator + dateString + ".zip";
boolean flag = FrameZipUtil.createZip(sourcePath, zipPath);
if(flag) {
codeCreateDao.updateFinish(codeCreate.getId(), download);
LOGGER.info("文件打包成功!");
} else {
LOGGER.info("文件打包失败!");
}
codeCreateDao.updateFinish(codeCreate.getId(), download);
}核心代码块
