002 Hello Spring Security

In front of the environment framework has been built, now in the demo module to write a simple case, let the whole environment run up.

One: Start the demo project

1. New class

Before this, build the package first.

　　

2. Start the class program

1  PackageCom.cao;2 3 Importorg.springframework.boot.SpringApplication;4 Importorg.springframework.boot.autoconfigure.SpringBootApplication;5 Importorg.springframework.web.bind.annotation.GetMapping;6 ImportOrg.springframework.web.bind.annotation.RestController;7 8 /**9 * Module Startup classTen  * @authorDell One  */ A@SpringBootApplication//Description This is a springboot project -@RestController//can provide rest services -  Public classApplicationdemo { the  -      Public Static voidMain (string[] args) { -         //Spring Standard boot mode -Springapplication.run (Applicationdemo.class, args); +     } -      +@GetMapping ("/hello") A      PublicString Hello () { at         return"Spring secutity Demo"; -     } -  -}

3. Start effect

The description does not specify a database.

　　

4. How to Solve

Although JDBC was introduced in the core, no configuration items were added to the project. Now add the database configuration item in the Demo module

New file

　　　　

Add a configuration item

1 spring.datasource.driver-class-name = Com.mysql.jdbc.Driver 2 spring.datasource.url= jdbc:mysql://127.0.0.1:3308/test?useunicode=yes&characterencoding =utf-8&usessl=false3spring.datasource.username = root4 Spring.datasource.password = 123456

5. Start again

The store for session is not specified.

　　

6. How to Solve

There is a session reference in the browser module, where the session is stored as none

　　

In the learning process, if the 8080 port is occupied, you can configure a configuration here (use 8080 here, just to do an example)

　　

7. Start again to start successfully

　　

Here is the default, in order to verify the demo, temporarily disable this through the configuration item.

　　

8. Final effect

　　

9. The application.properties at this time

1 # #JDBC2 spring.datasource.driver-class-name = Com.mysql.jdbc.Driver3Spring.datasource.url= Jdbc:mysql://127.0.0.1:3308/test?useunicode=yes&characterencoding=utf-8&usessl=false4 spring.datasource.username = root5 Spring.datasource.password = 1234566 7 # #session Store Type8 Spring.session.store-type=none9 Ten # #server Port One #server. port=8060 A  - # #security Login -Security.basic.enabled = False

Two: Packaging

1. Build on the parent project

　　

2. Watch each target

It can be found that this package does not provide a Web service because the package is too small.

　　

-----------------------------------------------------------------------

　　

3. How do I make a package that can be executed?

Add a build configuration to the demo module.
