## 新建项目
>新建一个maven quickstart项目：
>项目结构图：
>pom.xml文件:
```java
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
4.0.0

```
## 配置项目
>一、打开settings.xml，配置本地仓库：
```java
C:\Users\yangyp\.m2\libs
```
>二、在profiles下配置远程仓库（或自建仓库）地址：
```java
nexus
central
http://repo1.maven.org/maven2
true
false
central
http://repo1.maven.org/maven2
true
false
```
> **http://repo1.maven.org/maven2 为美国ip，速度比较慢**
>三、pom.xml配置：
```java
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

> Reimport项目后：
>controller:
```java
@RestController
@RequestMapping("/")
public class HelloController {
@RequestMapping("/hello")
public String PrintHello(){
return "hello world !";
}
@RequestMapping("/printMsg/{msg}")
// public String PrintPathVariable(@PathVariable String msg){
// return msg;
// }
public String PrintPathVariable(@PathVariable("msg") String paramMsg){
return paramMsg;
}
@RequestMapping("/requestParams")
public String PrintRequestParams(@RequestParam(name = "inputMsg",required = true) String inputMsg,@RequestParam(value = "username",required = false)String username){
String msg = "inputMsg :"+inputMsg+",username :"+username;
return msg;
}
@RequestMapping("/saveUser")
public String SaveUser(@RequestBody UserDto userDto){
return userDto.toString();
}
}
```
>运行测试：
>@PathVariable传参：
http://localhost:8080/printMsg/welcome
>@RequestParam传参：
运行成功！
spring.boot服务构建成功！
