Java 代码自动生成

Java代码生成

因为使用spring boot开发项目的时候，需要经常创建新的service，entity，repository等代码，而且很多都是重复性的代码，也就是说可以进行模板化生成的代码。跟mybatis的代码生成不一样，我只需要生成一个新文件，然后有一些初始化的代码就行，因此实现起来也很简单

package com.iotxing.crm.util;


import java.io.File;
import java.io.FileWriter;

@SuppressWarnings("unchecked")
public class CodeGenerate {
    /**

     */

    public static final String AUTHOR = "IOTXING";


    //package title
    public static final String ENTITYSRC = "com/iotxing/crm/model";
    public static final String SERVICESRC = "com/iotxing/crm/service";
    public static final String CONTROLLERSRC = "com/iotxing/crm/controller";
    public static final String REPOSITORYSRC = "com/iotxing/crm/repository";

    public static final String ENTITYPATH = "com.iotxing.crm.model";
    public static final String SERVICEPATH = "com.iotxing.crm.service";
    public static final String CONTROLLERPATH = "com.iotxing.crm.controller";
    public static final String REPOSITORYPATH = "com.iotxing.crm.repository";

    //创建实体类
    public static void createEntity(String entityName) throws Exception {
        String fileName = System.getProperty("user.dir") + "/src/main/java/" + ENTITYSRC + "/" + entityName + ".java";
        File file = new File(fileName);
        FileWriter fileWriter = new FileWriter(file);
        fileWriter.write("package " + ENTITYPATH + ";\r\n\n\n");
        fileWriter.write("public class " + entityName + " extends " + "BaseModel { \n\n");
        fileWriter.write(" //code generate by iotxing \n\n");
        fileWriter.write("\n\n\n");
        fileWriter.write("}");
        fileWriter.flush();
        fileWriter.close();
    }


    public static void createService(String serviceName) throws Exception {
        String fileName = System.getProperty("user.dir") + "/src/main/java/" + SERVICESRC + "/" + serviceName + ".java";
        File file = new File(fileName);
        FileWriter fileWriter = new FileWriter(file);
        fileWriter.write("package " + SERVICEPATH + ";\r\n\n\n");
        fileWriter.write("import org.springframework.stereotype.Service; \n\n\n");
        fileWriter.write("@Service\n");
        fileWriter.write("public class " + serviceName + " { \n\n");
        fileWriter.write(" //code generate by iotxing \n\n");
        fileWriter.write("\n\n\n");
        fileWriter.write("}");
        fileWriter.flush();
        fileWriter.close();
    }

    public static void createRepository(String entityName) throws Exception {
        String fileName = System.getProperty("user.dir") + "/src/main/java/" + REPOSITORYSRC + "/" + entityName + "Repository.java";
        File file = new File(fileName);
        FileWriter fileWriter = new FileWriter(file);
        fileWriter.write("package " + REPOSITORYPATH + ";\r\n\n\n");
        fileWriter.write("import " + ENTITYPATH +"."+entityName+ ";\r\n\n\n");
        fileWriter.write("public interface " + entityName + "Repository extends BaseRepository<"+entityName+",Long> { \n\n");

        fileWriter.write("}");

        fileWriter.close();
