Web 调用需要配置 jquery 组件，用到 ajax，需要配置 ajaxfileupload.js。

web 要视具体情况来编写代码，下面代码为核心调用部分。

$('#upfilebtn2').fileupload({

url : 'upload',

dataType : 'json',

formData : {

convertType : "0"

},

//如果需要额外添加参数可以在这里添加

done : function(e, data){

$.isLoading("hide");

}

});

$.ajax({

url : "onlinefile",

data :{

"downloadUrl" : obj_value,

"convertType" : "0"

},

dataType : "json",

type : "post",

success : function(data){

$.isLoading("hide");

},

error : function(data){

$.isLoading("hide");

console.error(data)

}

})

关于永中DCS文档转换中实例数的设置：我们一般推荐客户按照服务器的硬件条件来设置。例如服务器可用为 4 核配 8G 内存，并发可设置 4-8 个，我们推荐1核1G内存设置1个并发实例 。

tomcat的性能优化：根据设置的实例数和服务器剩余内存数来设置 jvm 的内存设置。

Ⅰ windows 下：

在windows下的tomcat/bin下的catalina.bat中首行加入set JAVA_OPTS=-Xms***m -Xmx***m

Ⅱ Linux 下：

在 linux下的tomcat/bin下的catalina.sh中首行加入 JAVA_OPTS="$JAVA_OPT -Xms***m -Xmx***m"

其中 Xms 表示启动所需最小内存，Xmx 表示可用最大内存，***根据实际情况设置
