1.Eclipse中安装STS插件:
Help -> Eclipse Marketplace…
Search或选择“Popular”标签,选择Spring Tool Suite (STS) for Eclipse插件,安装:
2.New -> Project…

找到Spring目录,选择Spring Starter Project,Next

3、填写跟项目相关的各种信息,然后Next
4.选择需要的Dependency,然后Next:
5.Next,然后Finsh,新项目就创建好了,各个目录如下:
6.右键MySpringBootApplication中的main方法,Run As -> Spring Boot App,项目就可以启动了。
package com.example;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class MySpringBootApplication {
public static void main(String[] args) {
SpringApplication.run(MySpringBootApplication.class, args);
}
}

由于选择了web dependency默认启动一个Tomcat,8080端口监听
7.把application.properties改名为application.yml(个人喜欢),修改Tomcat的启动端口:
server:
port: 8081

要SpringBoot进行功能开发,需要使用Gradle或者Maven作为构建工具。在本例中,我们会使用Eclipse和Maven插件进行开发。要使用SpringBoot,首先创建一个Maven工程,并修改Maven主要的配置文件pom.xml

在spring boot中,简单几步,读取配置文件(application.yml)中各种不同类型的属性值:
1、引入依赖:
?

123456

<!-- 支持 @ConfigurationProperties 注解 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-configuration-processor</artifactId> <optional>true</optional> </dependency>

2、配置文件(application.yml)中配置各个属性的值:
?

1234567891011121314

myProps: #自定义的属性和值 simpleProp: simplePropValue arrayProps: 1,2,3,4,5 listProp1: - name: abc value: abcValue - name: efg value: efgValue listProp2: - config2Value1 - config2Vavlue2 mapProps: key1: value1 key2: value2

3、创建一个bean来接收配置信息:
?

@Component @ConfigurationProperties(prefix="myProps") //接收application.yml中的myProps下面的属性 public class MyProps { private String simpleProp; private String[] arrayProps; private List<Map<String, String>> listProp1 = new ArrayList<>(); //接收prop1里面的属性值 private List<String> listProp2 = new ArrayList<>(); //接收prop2里面的属性值 private Map<String, String> mapProps = new HashMap<>(); //接收prop1里面的属性值 public String getSimpleProp() { return simpleProp; } //String类型的一定需要setter来接收属性值;maps, collections, 和 arrays 不需要 public void setSimpleProp(String simpleProp) { this.simpleProp = simpleProp; } public List<Map<String, String>> getListProp1() { return listProp1; } public List<String> getListProp2() { return listProp2; } public String[] getArrayProps() { return arrayProps; } public void setArrayProps(String[] arrayProps) { this.arrayProps = arrayProps; } public Map<String, String> getMapProps() { return mapProps; } public void setMapProps(Map<String, String> mapProps) { this.mapProps = mapProps; } }

启动后,这个bean里面的属性就会自动接收配置的值了。
4、单元测试用例:
?

1234567891011

@Autowired private MyProps myProps; @Test public void propsTest() throws JsonProcessingException { System.out.println("simpleProp: " + myProps.getSimpleProp()); System.out.println("arrayProps: " + objectMapper.writeValueAsString(myProps.getArrayProps())); System.out.println("listProp1: " + objectMapper.writeValueAsString(myProps.getListProp1())); System.out.println("listProp2: " + objectMapper.writeValueAsString(myProps.getListProp2())); System.out.println("mapProps: " + objectMapper.writeValueAsString(myProps.getMapProps())); }

测试结果:
?

12345
simpleProp: simplePropValue arrayProps: ["1","2","3","4","5"] listProp1: [{"name":"abc","value":"abcValue"},{"name":"efg","value":"efgValue"}] listProp2: ["config2Value1","config2Vavlue2"] mapProps: {"key1":"value1","key2":"value2"}
