SpringBoot性能调优有三种方案
SpringBoot 是一个快速开发框架,能够快速的整合第三方框架,简化XML配置,全部采用注解形式,内置Tomcat容器,帮助开发者能够实现快速开发,SpringBoot的Web组件 默认集成的是SpringMVC框架。
尽管 SpringBoot 拥有这么多的优点,但也存在性能问题,这并不和它拥有如此多的优点相冲突,应用程序性能只有更优,没有最优。
对于 SpringBoot 性能优化可以从注解 @SpringBootApplication 上优化,Servlet 容器上优化, JVM 上优化等等。我们分别从这三方面进行优化。
- 启动方式
- 启动容器
- jvm参数调优
一,启动方式优化注解 @SpringBootApplication
@SpringBootApplication 是Springboot 整合的一个复合注解,作用相当于 @Configuration + @EnableAutoConfiguration + @ComponentScan ,这个可以查看 @SpringBootApplication 源码得知,其中有一句 This is a convenience annotation that is equivalent to declaring {@code @Configuration},{@code @EnableAutoConfiguration} and {@code @ComponentScan} 说的就是这个意思。
