表示启动成功,这是就可以访问了 http://localhost:8080/greeting?name=xxb
会出现如下结果:
{"id":3,"content":"Hello,xuxiaobo!"}
这是一个纯java的项目,不需要启动tomcat也可以执行访问
First you set up a basic build script. You can use any build system you like when building apps with Spring, but the code you need to work with Maven is included here. If you’re not familiar with Maven, refer to Building Java Projects with Maven.
In a project directory of your choosing, create the following subdirectory structure; for example, with mkdir -p src/main/java/hello
on *nix systems:
└── src └── main └── java └── hello

The Spring Boot Maven plugin provides many convenient features:
It collects all the jars on the classpath and builds a single, runnable "über-jar", which makes it more convenient to execute and transport your service.
It searches for the public static void main()
method to flag as a runnable class.
It provides a built-in dependency resolver that sets the version number to match Spring Boot dependencies. You can override any version you wish, but it will default to Boot’s chosen set of versions.
