SpringBoot敏捷開發 使用動軟程式碼生成器 搞定三層架構程式碼
阿新 • • 發佈：2018-12-24
前言
首先介紹一下 我是一個寫過很多年.net 程式碼的程式設計師
2010年才轉的JAVA開發
所以一直對@李天平 .net大神級人物 心生崇拜
此人部落格地址為 https://blog.csdn.net/litp/
提到這個人 就不得不提起 動軟程式碼生成器 真乃神器也
但是JAVA web開發中 一直沒有一款順手的 程式碼生成器
後來公司胡總寫了一個 但是修改起來 非得有很強的技術實力不可
於是想到用這個動軟程式碼生成器來逆向生成SpringBoot 程式碼
具體模板使用方法請參考官方解釋
https://blog.csdn.net/litp/article/details/6445672
Entity模板
所有表名為 t_ 開頭 使用者表就是 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 //不建議在主表放置大型文字欄位 如果有 推薦使用 一對一關聯表存放" : "" #> 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"){ str2 = "Float"; }else if(type=="double"||type=="real"){ str2 = "Double"; }else if(type=="bigint"){ str2 = "Long"; }else if(type=="bit"){ str2 = "Boolean"; }else if(type=="date"||type=="datetime"||type=="timestamp"){ str2 = "Date"; } return str2; } private string getDefaultValueByType(string type){ string str2 = " = \"\""; if(type=="int"||type=="mediumint"||type=="integer"||type=="smallint"||type=="tinyint"){ str2 = " = 0"; }else if(type=="float"){ str2 = " = 0f"; }else if(type=="double"||type=="real"){ str2 = " = 0d"; }else if(type=="bigint"){ str2 = " = 0l"; }else if(type=="bit"){ str2 = " = false"; }else if(type=="date"||type=="datetime"||type=="timestamp"){ str2 = " = new Date()"; } return str2; } #>
Repository
生成 幾行程式碼而已啦 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)) #>; //請自行修改 @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 層程式碼
我寫了個介面和類 來對應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;
/**
* 基礎的Service 介面 繼承次介面 就有了 JPA了大部分方法
* @author shili
*
*/
public interface IService<T,ID extends Serializable> {
/**
* <p>
* 插入一條記錄 返回這個物件的實體
* </p>
*
* @param entity 實體物件
* @return T
*/
T insert(T entity);
/**
* <p>
* 插入多個實體
* </p>
*
* @param entityList 實體物件列表
* @return List
*/
List<T> insert(List<T> entityList);
/**
* <p>
* 更新操作 通過id
* </p>
* @param entity 實體物件列表
* @param id
* @return 這個物件
*/
T update(T entity, ID id);
/**
* <p>
* 更新操作 通過條件批量更新
* </p>
* @param 需要更新成啥樣 這個裡面是update 語句中 set部分
* @param 給定的條件是一個實體 實體中的欄位就是條件 這個是條件 不要弄反了 這個就是update 語句中 where部分
* @return 影響的條目數
*/
Integer update(T entity,T where);
/**
* <p>
* 根據 ID 刪除
* </p>
*
* @param id 主鍵ID
* @return boolean
*/
void delete(ID id);
/**
* <p>
* 根據 實體 刪除 符合這個實體中欄位條件的 都刪除
* </p>
*
* @param 給定的條件是一個實體 實體中的欄位就是條件
* @return 刪除的條目數
*/
Integer deleteByBody(T where);
/**
* <p>
* 通過條件批量刪除
* </p>
*
* @param id 主鍵ID
* @return T
*/
T findOne(ID id);
/**
* <p>
* 查詢（根據ID 批量查詢）
* </p>
*
* @param idList 主鍵ID列表
* @return List<T>
*/
List<T> findByIds(Iterable<ID> ids);
/**
* <p>
* 列出所有
* </p>
*
* @return List<T>
*/
List<T> findAll();
/**
* <p>
* 列出所有
* </p>
*
* @return Page<T>
*/
Page<T> findAll(Pageable pageable);
/**
* <p>
* 查詢（根據 Body 條件）
* </p>
*
* @param Body 物件實體
* @return List<T>
*/
List<T> findByBody(T t);
/**
* <p>
* 查詢（根據 Body）
* </p>
*
* @param Body 物件實體
* @return Page<T>
*/
Page<T> findByBody(T t,Pageable pageable);
/**
* <p>
* 查詢總記錄數
* </p>
*
* @param wrapper 實體物件
* @return Long
*/
Long count();
/**
* <p>
* 根據 Body 條件，查詢總記錄數
* </p>
*
* @param wrapper 實體物件
* @return Long
*/
Long count(T t);
}
實現
import java.io.Serializable;

public class ServiceImpl<M extends JpaRepository<T,ID>,T,ID extends Serializable> implements IService<T,ID> {
@Autowired
protected M dao;
@Override
public T insert(T entity) {
return dao.save(entity);
}
@Override

}
@Override

@Override

}生成程式碼模板 就超級簡單了 首先是介面
<#@ 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;
}
#>然後是實現
<#@ 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;
}
