开发知识-如何使用Tomcat架设webdav服务器

O2OA服务器支持使用webdav协议来存储二进制文件.
Tomcat默认是支持WebDAV的,且默认为禁用状态.
可以开启Tomcat的webdav作为文件存储服务器.
开启步骤如下:
1.在tomcat的webapp是目录下创建一个webdav目录作为项目.
2.在webdav目录下创建WEB-INF/web.xml
web.xml内容如下:

xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    id="WebApp_ID" version="3.0">
    <display-name>webdavdisplay-name>

3.在tomcat/conf目录下的tomcat-users.xml文件中添加webdav访问用户
4.启动Tomcat

xml version="1.0" encoding="UTF-8"?>
<tomcat-users xmlns="http://tomcat.apache.org/xml"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="http://tomcat.apache.org/xml tomcat-users.xsd"
              version="1.0">
  <role rolename="webdav"/>
  <user username="admin" password="admin" roles="webdav"/>
tomcat-users>

5.在o2server/configSample目录下拷贝externalStorageSources.json到o2server/config目录
修改配置指向webdav

}

6.在o2server/config目录下将node_xxx.xxx.xxx.xxx.json中的storage服务器设置为禁用.

  "storage": {
    "enable": false,
    "port": 20040.0,
    "sslEnable": false,
    "name": "251",
    "accounts": [],
    "prefix": "",
    "deepPath": false,
    "###enable": "是否启用,对于二进制流文件,比如附件,图片等存储在单独的文件服务器中,可以支持多种文件服务器,默认情况下使用ftp服务器作为文件服务器,每个节点可以启动一个文件服务器以提供高性能.###",
    "###port": "ftp服务器端口,此端口可以不对外开放,仅有ApplicationServer进行访问,并不直接对用户提供服务.###",
    "###sslEnable": "是否启用ssl传输加密,如果启用将使用config/keystore文件作为密钥文件.使用config/token.json文件中的sslKeyStorePassword字段为密钥密码,sslKeyManagerPassword为管理密码.###",
    "###name": "名称,多个节点中不能重名,默认为251.###",
    "###accounts": "二进制流文件是分多个账号分段存储的,可以单独设置每个分类的存储配置,一般不需要设置.###",
    "###passivePorts": "ftp传输有主动和被动之分,如果使用了被动传输,设置被动端口范围,默认为29000-30000.###",
    "###prefix": "路径前缀.###",
    "###deepPath": "使用更深的路径###"
  }

7.启动服务器o2server服务已经将存储转向tomcat服务器所提供的webdav服务.
tomcat-users.xml
webdav.zip
