SpringBoot敏捷开发 使用动软代码生成器 搞定三层架构代码
前言
首先介绍一下 我是一个写过很多年.net 代码的程序员
2010年才转的JAVA开发
所以一直对@李天平 .net大神级人物 心生崇拜
此人博客地址为 https://blog.csdn.net/litp/
提到这个人 就不得不提起 动软代码生成器 真乃神器也
但是JAVA web开发中 一直没有一款顺手的 代码生成器
后来公司胡总写了一个 但是修改起来 非得有很强的技术实力不可
于是想到用这个动软代码生成器来逆向生成SpringBoot 代码
具体模板使用方法请参考官方解释
https://blog.csdn.net/litp/article/details/6445672
Entity模板
所有表名为 t_ 开头 用户表就是 t_user
<#@ template language="c#" HostSpecific="True" #>
<#@ output extension= ".java" #>
<#
TableHost host = (TableHost)(Host);
host.Fieldlist.Sort(CodeCommon.CompareByintOrder);
boolean hasDefaultValue = true;
#>
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Lob;
import org.springframework.data.rest.core.annotation.RestResource;
import com.fasterxml.jackson.annotation.JsonIgnore;
@Entity
@Table(name="<#= host.GetModelClass(host.TableName) #>")
public class <#= getClassNameByTableName(host.GetModelClass(host.TableName)) #>{
<# foreach (ColumnInfo c in host.Fieldlist)
{ #>
<# if(c.IsPrimaryKey ){#>@Id
@GeneratedValue(strategy = GenerationType.AUTO)<#}#><#= c.TypeName=="longtext" ? @"@Lob //不建议在主表放置大型文本字段 如果有 推荐使用 一对一关联表存放" : "" #>
private <#= typeConvert(c.TypeName)#> <#= c.ColumnName.ToString()#><#=hasDefaultValue?getDefaultValueByType(c.TypeName):""#>;
<#}#>
<# foreach (ColumnInfo c in host.Fieldlist)
{ #>
public <#= typeConvert(c.TypeName)#> get<#= c.ColumnName.ToString().Substring(0,1).ToUpper()#><#= c.ColumnName.ToString().Substring(1)#>() {
return <#= c.ColumnName.ToString()#>;
}
public void set<#= c.ColumnName.ToString().Substring(0,1).ToUpper()#><#= c.ColumnName.ToString().Substring(1)#>(<#= typeConvert(c.TypeName)#> <#= c.ColumnName.ToString()#>) {
this.<#= c.ColumnName.ToString()#> = <#= c.ColumnName.ToString()#>;
}
<#}#>
}
<#+
//
private string getClassNameByTableName(string tname){
string str2 = "";
tname = tname.Replace("t_","");
for (int i = 0; i < tname.Length; i++) {
string temp = tname.Substring(i, 1);
if (temp == "_") {
temp = tname.Substring(i+1, 1).ToUpper();
i++;
}
if(i==0){
temp = temp.ToUpper();
}
str2 += temp;
}
return str2;
}
//mysql to java
//include varchar char longtext int bigint float double bit date real
//default type String
private string typeConvert(string type){
string str2 = "String";
if(type=="int"||type=="mediumint"||type=="integer"||type=="smallint"||type=="tinyint"){
str2 = "Integer";
}else if(type=="float"){

}
return str2;
}
private string getDefaultValueByType(string type){
string str2 = " = \"\"";
if(type=="int"||type=="mediumint"||type=="integer"||type=="smallint"||type=="tinyint"){

}
#>Repository
生成 几行代码而已啦 包含的Entity包名需要更改
<#@ template language="c#" HostSpecific="True" #>
<#@ output extension= ".java" #>
<#
TableHost host = (TableHost)(Host);
#>
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
import com.avicsafety.webapp.entity.<#= getClassNameByTableName(host.GetModelClass(host.TableName)) #>; //请自行修改
@Repository
public interface <#= getClassNameByTableName(host.GetModelClass(host.TableName)) #>Repository extends JpaRepository<<#= getClassNameByTableName(host.GetModelClass(host.TableName)) #>, Long> {
}
<#+
private string getClassNameByTableName(string tname){
string str2 = "";
tname = tname.Replace("t_","");
for (int i = 0; i < tname.Length; i++) {
string temp = tname.Substring(i, 1);
if (temp == "_") {
temp = tname.Substring(i+1, 1).ToUpper();
i++;
}
if(i==0){
temp = temp.ToUpper();
}
str2 += temp;
}
return str2;
}
#>Service 层代码
我写了个接口和类 来对应JPA常用方法
import java.io.Serializable;
import java.util.List;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
/**
* 基础的Service 接口 继承次接口 就有了 JPA了大部分方法
* @author shili
*
*/
public interface IService {
/**
*
* 插入一条记录 返回这个对象的实体
*
*
* @param entity 实体对象
* @return T
*/
T insert(T entity);
/**
*
* 插入多个实体
*
*
* @param entityList 实体对象列表
* @return List
*/
List insert(List entityList);
/**
*
* 更新操作 通过id
*
* @param entity 实体对象列表
* @param id
* @return 这个对象
*/
T update(T entity, ID id);
/**
*
* 更新操作 通过条件批量更新
*
* @param 需要更新成啥样 这个里面是update 语句中 set部分
* @param 给定的条件是一个实体 实体中的字段就是条件 这个是条件 不要弄反了 这个就是update 语句中 where部分
* @return 影响的条目数
*/
Integer update(T entity,T where);
/**
*
* 根据 ID 删除
*
*
* @param id 主键ID
* @return boolean
*/
void delete(ID id);
/**
*
* 根据 实体 删除 符合这个实体中字段条件的 都删除
*
*
* @param 给定的条件是一个实体 实体中的字段就是条件
* @return 删除的条目数
*/
Integer deleteByBody(T where);
/**
*
* 通过条件批量删除
*
*
* @param id 主键ID
* @return T
*/
T findOne(ID id);
/**
*
* 查询（根据ID 批量查询）
*
*
* @param idList 主键ID列表
* @return List
*/
List findByIds(Iterable ids);
/**
*
* 列出所有
*
*
* @return List
*/
List findAll();
/**
*
* 列出所有
*
*
* @return Page
*/
Page findAll(Pageable pageable);
/**
*
* 查询（根据 Body 条件）
*
*
* @param Body 对象实体
* @return List
*/
List findByBody(T t);
/**
*
* 查询（根据 Body）
*
*
* @param Body 对象实体
* @return Page
*/
Page findByBody(T t,Pageable pageable);
/**
*
* 查询总记录数
*
*
* @param wrapper 实体对象
* @return Long
*/
Long count();
/**
*
* 根据 Body 条件，查询总记录数
*
*
* @param wrapper 实体对象
* @return Long
*/
Long count(T t);
}
实现
import java.io.Serializable;
import java.util.List;
import org.springframework.beans.BeanUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Example;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.data.jpa.repository.JpaRepository;
import com.avicsafety.webapp.base.service.IService;
/**
* 其实Service 继承他就很好了
* @author shili
*
* @param Repository
* @param entity
* @param 主键类型
*/
public class ServiceImpl,T,ID extends Serializable> implements IService {
@Autowired
protected M dao;
@Override
public T insert(T entity) {
return dao.save(entity);
}
@Override
public List insert(List entities) {
return dao.save(entities);
}
@Override
public T update(T entity, ID id) {
T t= dao.findOne(id);
BeanUtils.copyProperties(entity, t);
return dao.save(t);
}
@Override
public void delete(ID id) {
dao.delete(id);;
}
@Override
public T findOne(ID id) {
return dao.findOne(id);
}
@Override
public List findByIds(Iterable ids) {
return dao.findAll(ids);
}
@Override
public List findAll() {
return dao.findAll();
}
@Override
public Page findAll(Pageable pageable) {
return dao.findAll(pageable);
}
@Override
public Long count() {
return dao.count();
}
@Override
public Long count(T t) {
return dao.count(Example.of(t));
}
@Override
public List findByBody(T t) {
return dao.findAll(Example.of(t));
}
@Override
public Page findByBody(T t,Pageable pageable) {
return dao.findAll(Example.of(t), pageable);
}
@Override
public Integer update(T entity, T where) {
List _list = findByBody(where);
for(T t:_list) {
BeanUtils.copyProperties(entity, t);
}
dao.save(_list);
return _list.size();
}
@Override
public Integer deleteByBody(T where) {
List _list = findByBody(where);
dao.delete(_list);
return _list.size();
}
} 生成代码模板 就超级简单了 首先是接口
<#@ template language="c#" HostSpecific="True" #>
<#@ output extension= ".java" #>
<#
TableHost host = (TableHost)(Host);
#>
public interface <#= getClassNameByTableName(host.GetModelClass(host.TableName)) #>Service extends IService<<#= getClassNameByTableName(host.GetModelClass(host.TableName)) #>,Long> {
}
<#+
private string getClassNameByTableName(string tname){
string str2 = "";
tname = tname.Replace("t_","");
for (int i = 0; i < tname.Length; i++) {
string temp = tname.Substring(i, 1);
if (temp == "_") {
temp = tname.Substring(i+1, 1).ToUpper();
i++;
}
if(i==0){
temp = temp.ToUpper();
}
str2 += temp;
}
return str2;
}
#>然后是实现
<#@ template language="c#" HostSpecific="True" #>
<#@ output extension= ".java" #>
<#
TableHost host = (TableHost)(Host);
#>
import org.springframework.stereotype.Service;
public class <#= getClassNameByTableName(host.GetModelClass(host.TableName)) #>ServiceImpl extends ServiceImpl<<#= getClassNameByTableName(host.GetModelClass(host.TableName)) #>Repository,<#= getClassNameByTableName(host.GetModelClass(host.TableName)) #>,Long> implements IStockService{
}
<#+
private string getClassNameByTableName(string tname){
string str2 = "";
tname = tname.Replace("t_","");
for (int i = 0; i < tname.Length; i++) {
string temp = tname.Substring(i, 1);
if (temp == "_") {
temp = tname.Substring(i+1, 1).ToUpper();
i++;
}
if(i==0){
temp = temp.ToUpper();
}
str2 += temp;
}
return str2;
}
