说明
Java中使用freemarker根据模版来生成具有一定格式的文件。本例以java动态生成 hibernate的*.hbm.xml文件为例子，并且假设已经导入了freemarker .jar文件
工具类
接口Render‘’
public interface Render {
void render(RenderClass target,String template,String outpath);
}
基本类bean RenderClass
import java.util.List;
public class RenderClass {
private String className;
private String tableName;
private String classPath;
private List properties;
public RenderClass()
{
properties = null;
}
public String getClassName() {
return className;
}
public void setClassName(String className) {
this.className = className;
}
public String getTableName() {
return tableName;
}
public void setTableName(String tableName) {
this.tableName = tableName;
}
public List getProperties() {
return properties;
}
public void setProperties(List properties) {
perties = properties;
}
public void setClassPath(String classPath) {
this.classPath = classPath;
}
public String getClassPath() {
return classPath;
}
}
基本类bean RenderProperty
package j.table.function;
/*?????????????????*/
public class RenderProperty extends BuildProperty{
private boolean primary;
private String name;
private String type;
private String sequence;
private Integer length;
private String field;
/* …省略set跟get方法…*/
}
