Springboot讀取配置文件及自定義配置文件的方法
1.創(chuàng)建maven工程,在pom文件中添加依賴
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.9.RELEASE</version> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!-- 單元測(cè)試使用 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <scope>test</scope> </dependency> </dependencies>
2.創(chuàng)建項(xiàng)目啟動(dòng)類 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 //自動(dòng)加載配置信息 @ComponentScan("com.kelly")//使包路徑下帶有注解的類可以使用@Autowired自動(dòng)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 //自動(dòng)加載配置信息 @ComponentScan("com.kelly")//使包路徑下帶有注解的類可以使用@Autowired自動(dòng)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.打開瀏覽器,輸入 http://localhost:8081/springboot/hello 即可看到結(jié)果
6.使用java bean的方式讀取自定義配置文件 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.打開瀏覽器,訪問(wèn) http://localhost:8081/springboot/define,可以看到輸出結(jié)果
