Problems with uploading pictures

Today, when using the SSM framework for uploading pictures, I met a question:

650) this.width=650; "Src=" https://s3.51cto.com/wyfs02/M00/A4/A6/wKioL1mvUALhJpsXAAGUZ3NP-TU727.png-wh_500x0-wm_ 3-wmp_4-s_206549125.png "title=" capture. PNG "alt=" Wkiol1mvualhjpsxaaguz3np-tu727.png-wh_50 "/>

Later check found is missing in the SPRINGMVC configuration file on the image upload configuration file

650) this.width=650; "Src=" https://s5.51cto.com/wyfs02/M01/05/F6/wKiom1mvUO-B0AibAADgqI4Wazo833.png-wh_500x0-wm_ 3-wmp_4-s_936553044.png "title=" capture. PNG "alt=" Wkiom1mvuo-b0aibaadgqi4wazo833.png-wh_50 "/>

Put the above <bean> configuration is OK;

By the way, summarize:

There are only three things to remember when uploading pictures:

1. Front page: (1) to use POST request; (2) Don't forget to add enctype= "Multipart/form-data" to the form form

2. Background controller layer to write this:

   650) this.width=650; "Src=" https://s3.51cto.com/wyfs02/M00/05/F6/wKiom1mvUk6TSklOAAEWzHJXR5o979.png-wh_500x0-wm_ 3-wmp_4-s_4218534918.png "title=" capture. PNG "alt=" Wkiom1mvuk6tskloaaewzhjxr5o979.png-wh_50 "/>
   

3. If the above code is not a problem, check the SPRINGMVC configuration file;
