篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了带界面的代码生成器相关的知识，希望对你有一定的参考价值。
代码生成器
1.项目gitthub地址链接: https://github.com/baisul/generateCode.git切换到master分支
2.环境
2.1 springboot+freemarker+mysql
2.2 要装node.js,vue文件运行依赖node.js
3.以下就只拿生成java实体类来作为例子
4.application.xml
server.port=8080
spring.datasource.url=jdbc:mysql://localhost:3306/demo?useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai
spring.datasource.username=root
spring.datasource.password=root
5.pom.xml

6.Utils
package com.yl.generate_code.utils;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
public class CORFSConfiguration extends WebMvcConfigurerAdapter {
@Override
public void addCorsMappings(CorsRegistry registry) {
//所有请求都允许跨域
registry.addMapping("/**")
.allowedOrigins("*")
.allowedMethods("*")
.allowedHeaders("*");
}
}
package com.yl.generate_code.utils;
import com.yl.generate_code.model.Db;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class DBUtils {
private static Connection connection;
public static Connection getConnection() {
return connection;
}
public static Connection init(Db db) {
if (connection == null) {
try {
Class.forName("com.mysql.cj.jdbc.Driver");
connection = DriverManager.getConnection( db.getUrl(),db.getUsername(), db.getPassword());
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
}
return connection;
}
}
7.生成模板
package ${packetName}.model;
import java.util.Date;
/**
* @Description: ${modelName}实体类
* @Author: wfj
* @CreateDate ${createDate}
* @Version: 1.0V
*/
public class ${modelName} {
<#if columns??>
<#list columns as column>
<#if column.type='VARCHAR' || column.type='TEXT' || column.type='CHAR'>
/**
* ${column.remark}
*/
private String ${column.propertyName?uncap_first};
</#if>
<#if column.type='INT'>
/**
* ${column.remark}
*/
private Integer ${column.propertyName?uncap_first};
</#if>
<#if column.type='DATETIME'>
/**

*/

</#if>
<#if column.type='BIGINT'>

*/
private Long ${column.propertyName?uncap_first};
</#if>
<#if column.type='DOUBLE'>
/**

*/
private Double ${column.propertyName?uncap_first};
</#if>
<#if column.type='BIT'>
/**

*/
private Boolean ${column.propertyName?uncap_first};
</#if>
</#list>
<#list columns as column>
<#if column.type='VARCHAR' || column.type='TEXT' || column.type='CHAR'>
public String get${column.propertyName}() {
return ${column.propertyName?uncap_first};
}
public void set${column.propertyName}(String ${column.propertyName?uncap_first}) {

}
</#if>

</#if>
