introduction

I was an old programmer who used eclipse and myeclipse all the time. Many of my fans said they wanted to use ideas and asked me why I didn’t use ideas. I learned more Java knowledge and practiced more, but as a fan fan, how could I refuse the request of fans, so I secretly learned a wave (bring it to you), and then wrote this series, I hope Friends can gain something, Brother Ming will work hard to update.

overview

If you import a web project developed by others in IDEA, here I will explain the steps in detail. Of course, the method will be slightly different for different frameworks and scenarios, but the general direction is similar.

1. Import project

Select Import on the welcome screen

2. Select the root directory of the code
3. Open the project structure

Check the jdk version and output directory, I usually use jdk1.6 1.8

Check the library file, if not, add it yourself, pay attention to the path

Configure tomcat, for example, it used to be 7, but now there is no 7, as long as 6, it needs to be reconfigured ( note here that if it is tomcat6, jdk cannot be configured with 1.8, it must be configured as 1.6, 1.8tomcat6 does not support it, and it will be encountered later in the article )

This is a red flag, so it needs to be reconfigured

Configure the correct tomcat and modify the name

Check deployment

If the javax.servlet.http package does not exist, you need to reset tomcat

Open the project structure, select the Modules option, then select your project, select Dependencies on the right, add the correct tomcat configuration, delete the red and useless tomcat7, and then apply the settings (if the application does not take effect, rebuild the project) .

Second, modify the database configuration

Look at my own situation, I use c3p0 here, and modify it accordingly

Build a database and create tables

3. Start tomcat

An error occurred

org.apache.jasper.compiler.JDTCompiler$1 findType
严重: Compilation error
org.eclipse.jdt.internal.compiler.classfmt.ClassFormatException

It turns out that tomcat6 does not support jdk1.8, which is very embarrassing. It is also possible to download a tomcat7, or to modify the compilation environment of jdk, depending on your preferences.

What I use here is to modify jdk to 1.6 (there are several places to modify)

Recompile the project

Restart tomcat6, then enter the address to access
