当前使用版本(必填,否则不予处理)
3.4.1
该问题是如何引起的？(确定最新版也有问题再提!!!)
AutoGenerator mpg ; GlobalConfig globalConfig = new GlobalConfig(); globalConfig.setServiceName("%sService");
mpg.setGlobalConfig(globalConfig);
mpg.setTemplateEngine(new FreemarkerTemplateEngine());
mpg.execute();
修改Service命名规则，然后就失败了
重现步骤(如果有就写完整)
AutoGenerator mpg = this.getAutoGenerator();
final PackageConfig pc = new PackageConfig();
pc.setParent(packageName);
pc.setEntity("pojo");
mpg.setPackageInfo(pc);
InjectionConfig cfg = new InjectionConfig() {
public void initMap() {
}
};
List
GlobalConfig globalConfig = new GlobalConfig();
globalConfig.setServiceName("%sService");
mpg.setGlobalConfig(globalConfig);
mpg.setTemplateEngine(new FreemarkerTemplateEngine());
mpg.execute();

globalConfig.setOutputDir(System.getProperty("user.dir") + "/src/main/java"); globalConfig.setAuthor("jobob"); 忘记加了，已解决
