There are two ways of spring boot hot deployment

1. Springloader plug-in

Disadvantages: Java code does deployment processing. But there's nothing you can do about the page.

2. Devtools

Fully automated deployment

The difference between spring loader and devtools: spring loader: hot deployment is used when deploying the project. Devtools: the redeployment method is used when deploying the project

The second is exactly redeployment. This blog mainly introduces the second, so this article uses "hot"

The devtools tool uses:

Add dependency in POM file

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <optional>true</optional>
</dependency>

This is no problem in eclipse, but the idea (PJ, emmm) used by bloggers found it useless, and then there was a wave of Baidu + Google

Finally, the solution is as follows:

Then shift + Ctrl + Alt + /, select registry

After entering, find the option shown in the figure below and check it

Then configure in the configuration file

spring.devtools.restart.poll-interval=3000ms
spring.devtools.restart.quiet-period=2999ms
