Internet Programming Notes and Records

Previous Project Experience

  1. Use Java to develop and optimize a simple motion scheduling and path planning algorithm for industrial machine (during work).
    Mainly based on the A* algorithm.
  2. Use Java to develop a multi-layer encryption cloud storage software (during undergraduate period)
  3. Design and development of an Online Mobile Market System

Practical homework tips: CI6206

  1. When use the higher version of tomcat (like version 8.5), it is very likely to happen this situation: the console report connection failure with database. One way to fix that is to use the new/lastest version of mysql connnector (like fullname is [mysql-connector-java-8.0.21.jar]).

Preparation

  1. aliahmadi4/WAP-SocialNetwork - Rejected
    No time to get familiar to IDEA in such short time

  2. asaunin/social-network-spring - Rejected
    No time to get familiar to Spring MVC

  3. Sathveegan/Social-App-JAVA-Servlet-JSP - Choosen
    deployment: 1) fix database problem by change mysql.jar version to V8.0

             2) change all jsp file into the "/WebContent"
         3) after putting image or external files, should refresh the project in eclipse to make the changes valid.

Addtional functions

  1. Upload image as personal avatar
    Bunoob.com example of upload file
    “Server Tomcat v8.5 Server at localhost failed to start” - because I changed xml in code

  2. Search function
    Tips: 1) slides and example from class

       2) Should delete the line "Collections.sort(searchUsers);" in UserDAO, which would cause the return value of function "getUsersByName" be null and cause error. The real cause is that the sort function would fail when there is several same value of names.
   3) [bootstrap table setting](https://blog.csdn.net/Fanbin168/article/details/53208869) / [runoob document](https://www.runoob.com/bootstrap/bootstrap-tables.html)
