org.springframework.boot
spring-boot-starter-parent
1.5.9.RELEASE
org.springframework.boot
spring-boot-starter-web
org.springframework.boot
spring-boot-starter-test
junit
junit
test
2.创建项目启动类 StartApplication.java
package com.kelly.controller;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
@Configuration
@EnableAutoConfiguration //自动加载配置信息
@ComponentScan("com.kelly")//使包路径下带有注解的类可以使用@Autowired自动注入
public class StartApplication {
public static void main(String[] args) {
SpringApplication.run(StartApplication.class, args);
}
}
package com.kelly.controller;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
@Configuration
@EnableAutoConfiguration //自动加载配置信息
@ComponentScan("com.kelly")//使包路径下带有注解的类可以使用@Autowired自动注入
public class StartApplication {
public static void main(String[] args) {
SpringApplication.run(StartApplication.class, args);
}
}
package com.kelly.controller;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class FirstController {
@Value("${test.name}")
private String name;
@Value("${test.password}")
private String password;
@RequestMapping("/")
@ResponseBody
String home()
{
return "Hello Springboot!";
}
@RequestMapping("/hello")
@ResponseBody
String hello()
{
return "name: " + name + ", " + "password: " + password;
}
}5.打开浏览器，输入 http://localhost:8081/springboot/hello 即可看到结果
6.使用java bean的方式读取自定义配置文件 define.properties
DefineEntity.java
package com.kelly.entity;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;
@Component
@ConfigurationProperties(prefix="defineTest")
@PropertySource("classpath:define.properties")
public class DefineEntity {
private String pname;
private String password;
public String getPname() {
return pname;
}
public void setPname(String pname) {
this.pname = pname;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
SecondController.java
package com.kelly.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.kelly.entity.DefineEntity;
@Controller
public class SecondController {
@Autowired
DefineEntity defineEntity;
@RequestMapping("/define")
@ResponseBody
String define()
{
return "test.name:" + defineEntity.getPname() + ", test.password:" + defineEntity.getPassword();
}
}7.打开浏览器，访问 http://localhost:8081/springboot/define，可以看到输出结果
补充：我的项目的目录结构
