how to limit uploaded filesize in tomcat servlet
提问by somtomas
I need to set max filesize for uploaded files in my servlet running on tomcat. I tried multipart config which worked on jetty, but tomcat just ignored it. It means deployment on tomcat server caused even big files can be uploaded. My configuration:
我需要为在 tomcat 上运行的 servlet 中上传的文件设置最大文件大小。我尝试了在码头上工作的多部分配置，但 tomcat 只是忽略了它。这意味着部署在tomcat服务器上导致甚至可以上传大文件。我的配置：
<servlet>
<servlet-name>myServlet</servlet-name>
<servlet-class>sk.test.MyServlet</servlet-class>
<multipart-config>
<max-file-size>1048576</max-file-size>
<max-request-size>104857600</max-request-size>
</multipart-config>
</servlet>
I already tried annotated configuration, which didnt work too.
我已经尝试过带注释的配置，但也不起作用。
Using: Tomcat 7.0.54, Servlet 3.0
使用：Tomcat 7.0.54，Servlet 3.0

Set value of max file size, use annotation before servlet class or web.xmlconfig.
See maxFileSizein annotation or <max-file-size></max-file-size>in xml config.
设置最大文件大小的值，在 servlet 类或web.xml配置之前使用注释。请参阅maxFileSize注释或<max-file-size></max-file-size>xml 配置。
@MultipartConfig(
location="/tmp",
fileSizeThreshold=1024*1024, // 1 MB
maxFileSize=1024*1024*5, // 5 MB
maxRequestSize=1024*1024*5*5 // 25 MB
)
or
或者
<multipart-config>
<location>/tmp</location>
<max-file-size>20848820</max-file-size>
<max-request-size>418018841</max-request-size>
<file-size-threshold>1048576</file-size-threshold>
</multipart-config>
