项目中经常需要进行一些配置，一般会使用springboot默认的application.properties文件，也可以自己创建配置文件
一，application.properties配置
logging.path=/Users/zhang_guang_yang/IDEA15/Logs/ logging.file=SpringBoot.log # strings com.gy.dateFormatter=dd-MM-yyyy # strings com.pleasure.local=/files # array com.pleasure.urls[0]=http://www.baidu.com/ com.pleasure.urls[1]=http://www.google.com/ com.pleasure.urls[2]=http://www.blog.csdn.com/ # map com.pleasure.admin[username]=pleasure com.pleasure.admin[password]=123456
读取
1，通过一个配置类来读取：
package com.example.demo.config;
import org.springframework.boot.autoconfigure.session.StoreType;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
/**
* Created by zhang_guang_yang on 2018/12/2.
*/
@Component
@ConfigurationProperties(prefix = "com.pleasure")
public class AppProperties {
private String local;
private Map<String, String> admin = new HashMap<String ,String>();
private List<String> urls = new ArrayList<String >();
public String getLocal() {
return local;
}
public void setLocal(String local) {
this.local = local;
}
public Map<String, String> getAdmin() {
return admin;
}
public void setAdmin(Map<String, String> admin) {
this.admin = admin;
}
public List<String> getUrls() {
return urls;
}
public void setUrls(List<String> urls) {
this.urls = urls;
}
}
获取属性
@RestController
@EnableAutoConfiguration
public class PropertiesController {
@Autowired
private AppProperties appProperties;
@RequestMapping("/properties")
public String properties(){
System.out.println("local: " + appProperties.getLocal());
System.out.println("admin: " + appProperties.getAdmin().get("username")；
return success;
}
}
2, @Value读取
@Value("${com.gy.dateFormatter}")
private String dateFormat;
3，通过Environment对象读取
@Autowired
private Environment evn;
整个实现
package com.example.demo.controllers;
import com.example.demo.config.AppProperties;
import com.example.demo.domain.Info;
import com.sun.tools.javac.comp.Env;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.core.env.Environment;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* Created by zhang_guang_yang on 2018/11/20.
*/
@RestController
@EnableAutoConfiguration
public class PropertiesController {
@Autowired
private AppProperties appProperties;
@Value("${com.gy.dateFormatter}")
private String dateFormat;
@Autowired
private Environment evn;
@Autowired
private Info info;
@RequestMapping("/properties")
public String properties(){
System.out.println("local: " + appProperties.getLocal());
System.out.println("admin: " + appProperties.getAdmin().get("username") + " " + appProperties.getAdmin().get("password"));
System.out.println("url: " + appProperties.getUrls().get(0));
System.out.println("date formatter: " + dateFormat);
System.out.println(evn.getProperty("com.gy.dateFormatter"));
System.out.println("info: " + info.getName());
return "success";
}
}
二，自定义properties文件和类
1，info.properties
zgy.info.version=1.0 zgy.info.name="good mall" zgy.info.bundleId="zgy.good.mall"
2, 定义类
package com.example.demo.domain; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.PropertySource; /** * Created by zhang_guang_yang on 2018/11/20. */ @ConfigurationProperties(prefix = "zgy.info") @PropertySource("classpath:config/info.properties") public class Info { private String version; private String name; private String bundleId; public String getVersion() { return version; } public void setVersion(String version) { this.version = version; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getBundleId() { return bundleId; } public void setBundleId(String bundleId) { this.bundleId = bundleId; } }
3，注册扫描
@ComponentScan(basePackages = {"com.example.demo.domain"})
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
4，获取属性
@Autowired
private Info info;
