import org.springframework.boot.context.properties.NestedConfigurationProperty;
import org.springframework.context.annotation.Configuration;/*** author Lensen* desc* since 2018/8/22 12:59*/
Configuration
ConfigurationProperties(prefix one-app)
public class OneAppConfig {NestedConfigurationPropertypublic Account account new Account();public String appName;public Account getAccount() {return account;}public void setAccount(Account account) {this.account account;}public String getAppName() {return appName;}public void setAppName(String appName) {this.appName appName;}public class Account {private String username;private String password;private String age;public String getUsername() {return username;}public void setUsername(String username) {this.username username;}public String getPassword() {return password;}public void setPassword(String password) {this.password password;}public String getAge() {return age;}public void setAge(String age) {this.age age;}}
}很明显这就是我们要在properties文件中要配置的配置项。 再看第二种方式 /*** author Lensen* desc* since 2018/8/22 13:19*/
Configuration
public class TwoAppConfig {Value(${two-app.welcome.message})public String twoAppWelcomeMessage;Value(${two-app.welcome.person})public String twoAppWelcomePerson;public String getTwoAppWelcomeMessage() {return twoAppWelcomeMessage;}public void setTwoAppWelcomeMessage(String twoAppWelcomeMessage) {this.twoAppWelcomeMessage twoAppWelcomeMessage;}public String getTwoAppWelcomePerson() {return twoAppWelcomePerson;}public void setTwoAppWelcomePerson(String twoAppWelcomePerson) {this.twoAppWelcomePerson twoAppWelcomePerson;}
}这个就简单粗暴啦。没有第一种方式结构那么清晰具体怎么使用完全取决于项目配置项的关联关系和复杂度需要大家根据实际情况权衡。 接下来我写了个简单的测试类来获取我们的配置信息 先看配置文件 one-app:app-name: OneAPPaccount:username: Lensenpassword: Orclage: 22two-app:welcome:message: welcome to lensens bolgperson: LENSEN一个简单的Controller类 package com.developlee.customconfig.controller;import com.developlee.customconfig.config.OneAppConfig;
import com.developlee.customconfig.config.TwoAppConfig;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;/*** author Lensen* desc* since 2018/8/22 16:40*/
RestController
public class AppController {Autowiredprivate OneAppConfig oneAppConfig;Autowiredprivate TwoAppConfig twoAppConfig;GetMapping(/hello)public ResponseEntity getConfig() {String str1 oneAppConfig: oneAppConfig.getAppName() oneAppConfig.getAccount().getUsername() oneAppConfig.getAccount().getPassword() oneAppConfig.getAccount().getAge();String str2 twoAppConfig: twoAppConfig.getTwoAppWelcomePerson() twoAppConfig.getTwoAppWelcomeMessage();return new ResponseEntity(str1 ~~~~~~~ str2, HttpStatus.OK);}
}在地址栏输入http:localhost:8080/hello, 回车 也可以自己指定文件只需在类上加上注解PropertySource注解就好了~~ Configuration
PropertySource(classpath:my.properties)
public class ThreeConfig {Value(${my.name})private String myName;public String getMyName() {return myName;}public void setMyName(String myName) {this.myName myName;}
}my.properties文件内容 my.namedeveloplee测试结果 如果配置文件是yml格式的则要使用YamlPropertiesFactoryBean来加载并设置到PropertySourcesPlaceholderConfigurer中 // 加载YML格式自定义配置文件Beanpublic static PropertySourcesPlaceholderConfigurer properties() {PropertySourcesPlaceholderConfigurer configurer new PropertySourcesPlaceholderConfigurer();YamlPropertiesFactoryBean yaml new YamlPropertiesFactoryBean();yaml.setResources(new FileSystemResource(config.yml));//File引入
// yaml.setResources(new ClassPathResource(youryml.yml));//class引入configurer.setProperties(yaml.getObject());return configurer;end... 浮躁的社会浮躁的人生唯有代码宁静致远。又开始装13了,见谅..... 最后以上示例代码可在我的github.com中找到。 我的个人公众号developlee的潇洒人生。 关注了也不一定更新更新就不得了了。 转载于:https://my.oschina.net/liululee/blog/2250330
