基于模板的通用代码生成器LKGenerator(三)-模板示例

 
阅读更多

本代码生成工具提供的是一个生成代码的平台,各种不同形式的模板都可以在其上使用用于生成代码,模板的书写您需要遵循一定的规则(这些规则是velocity语法和本工具提供的变量,您可在上一篇中找到这些变量),只要您的模板符合这些规则就能用于生成代码.类比一下,淘宝为商家提供的是一个买卖交易的平台,各种各样的产品都可以在上面交易,买家和买家在交易时需要遵循一定的交易规则,只要大家都遵从这些规则就能很好的进行交易.当然把本工具比作淘宝显然不太恰当,本代码生成器远远比不上淘宝带给社会的价值,但真心希望本工具能给程序员带来一点点方便,也算她的一点点价值体现吧.

本代码生成工具之所以说具有通用性,在于它能生成各种语言的代码,模板是什么语言生成的代码就是什么语言.下面就举几个不同的模板示例分别生成代码.如果您看了上一篇文章您就应该知道,我们首先需要手写或用工具生成一个java文件,并将其编译为class.如下:

import java.util.*;
import com.tgb.lk.annotation.*;

@AutoBean(alias = "Student",table="t_student")
public class Student {


  @AutoField(alias = "序号", column = "id", isKey = true , isRequired = true , type="String", length=36)
  @ExcelVOAttribute(name = "id", column = "A")
  private String id;

  @AutoField(alias = "姓名", column = "name", isRequired = true, length = 255)
  @ExcelVOAttribute(name = "name", column = "B")
  private String name;

  @AutoField(alias = "性别", column = "sex", combo = {"男","女"}, length = 255)
  @ExcelVOAttribute(name = "sex", column = "C")
  private String sex;

  @AutoField(alias = "年龄", column = "age", type = "Integer")
  @ExcelVOAttribute(name = "age", column = "D")
  private int age;

  @AutoField(alias = "生日", column = "birthday", type = "Date")
  @ExcelVOAttribute(name = "birthday", column = "E")
  private Date birthday;

  @AutoField(alias = "班级ID", column = "clazz_id", length = 36)
  @ExcelVOAttribute(name = "clazz_id", column = "F")
  private String clazzId;

  @AutoField(alias = "是否班长", column = "is_monitor")
  @ExcelVOAttribute(name = "is_monitor", column = "G")
  private Boolean isMonitor;

  @AutoField(alias = "创建", column = "create_time", isRequired = true, type = "Date")
  @ExcelVOAttribute(name = "create_time", column = "H")
  private Date createTime;

  @AutoField(alias = "修改时间", column = "update_time", isRequired = true, type = "Date")
  @ExcelVOAttribute(name = "update_time", column = "I")
  private Date updateTime;



  public String getId() {
    return id;
  }
  public void setId(String id){
    this.id = id;
  }
  public String getName() {
    return name;
  }
  public void setName(String name){
    this.name = name;
  }
  public String getSex() {
    return sex;
  }
  public void setSex(String sex){
    this.sex = sex;
  }
  public int getAge() {
    return age;
  }
  public void setAge(int age){
    this.age = age;
  }
  public Date getBirthday() {
    return birthday;
  }
  public void setBirthday(Date birthday){
    this.birthday = birthday;
  }
  public String getClazzId() {
    return clazzId;
  }
  public void setClazzId(String clazzId){
    this.clazzId = clazzId;
  }
  public Boolean getIsMonitor() {
    return isMonitor;
  }
  public void setIsMonitor(Boolean isMonitor){
    this.isMonitor = isMonitor;
  }
  public Date getCreateTime() {
    return createTime;
  }
  public void setCreateTime(Date createTime){
    this.createTime = createTime;
  }
  public Date getUpdateTime() {
    return updateTime;
  }
  public void setUpdateTime(Date updateTime){
    this.updateTime = updateTime;
  }
}


以下模板您只需放到D:\.LKGenerator\templates-var模板根路径下即可运行查看使用效果.

(1) java的模板(${bean.Uname}.java): 

package ${base-package}.model;

import java.util.*;
import javax.persistence.*;
import com.tgb.lk.util.base.model.BaseTimeModel;
import com.tgb.lk.util.excel.ExcelVOAttribute;

@Entity
@Table(name = "t_${bean}")
public class ${bean.Uname} extends BaseTimeModel{
	
#set ( $arr = ['A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'] )

#foreach ($field in ${bean.fields})
#if(${field.isRequired})
	@Column(name = "${field}", nullable = false)
#else
	@Column(name = "${field}")
#end
	@ExcelVOAttribute(name = "${field.alias}", column = "$arr[$velocityCount]")
	private ${field.type} ${field};

#end

	public ${bean.Uname}() {
	}
	
#foreach ($field in ${bean.fields})
	public ${field.type} get${field.Uname}() {
		return ${field};
	}

	public void set${field.Uname}(${field.type} ${field}) {
		this.${field} = ${field};
	}
#end

}
