• word模板
  图片中的参数{{param}}对应上面controller中map的key值
  
• 导出后
  好处就是不会因为替换数据导致样式有所改变
  

print_r('新人小白，点个赞吧')；
var_dump('新人小白，点个赞吧')；
NSLog(@"新人小白，点个赞吧！")
System.out.println("新人小白，点个赞吧!");
console.log("新人小白，点个赞吧!");
print("新人小白，点个赞吧!");
printf("新人小白，点个赞吧!\n");

fmt.Println("新人小白，点个赞吧!")
Response.Write("新人小白，点个赞吧")；
alert（’新人小白，点个赞吧’）
