What is hot deployment?
- For the spring boot project, modify the java class in the background, do not restart the entire project, you can test/use the newly modified function!
How to add/set up hot deployment for the project
- The maven project adds the following code in pom.xml, and introduces new dependencies on the Internet.
<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-devtools -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<version>1.5.12.RELEASE</version>
</dependency>
- The gradle project adds the following code in build.gradle to introduce new dependencies online.
// https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-devtools
compile group: 'org.springframework.boot', name: 'spring-boot-devtools', version: '1.5.12.RELEASE'
Some Problems:
- Is the hot deployment complete?
- It's as simple as that when it's done, after all, spring boot
- how to use?
- After starting the project, try to modify the java code, such as changing the business logic in the service layer, outputting some console information, etc. (modifying the lower-level code such as mybatis sql, database corresponding entities, enumeration classes, etc. will cause hot deployment to fail or be invalid)
- Click the
Build Projectbutton (on the left side of the project start button, the shortcut key is ctrl+f9)
- After about 2 seconds, the lower left corner of the idea prompts xx classes reloaded
- The modified new features are ready to use!
- How to modify
Build Projectshortcut keys?
