SpringBoot 4種類のpropertiesファイルを読み込む方法
28553 ワード
前言
プロジェクト開発ではプロファイルが頻繁に使用され、プロファイルの存在によって大きな重複作業が解決されます.今日はSpringbootでプロファイルを取得する方法を4つ共有します.
注意:最初の3つのテストプロファイルはspringbootのデフォルトのアプリケーションです.propertiesファイル

com.zyd.type=Springboot - @Value
com.zyd.title= @Value
####################### #########################
com.zyd.type2=Springboot - Environment
com.zyd.title2= Environment 一、@ConfigurationProperties方式
カスタム構成クラス:PropertiesConfig.java
package com.zyd.property.config;
import java.io.UnsupportedEncodingException;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import org.springframework.boot.context.properties.ConfigurationProperties;
//import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;
/**

* @since JDK ： 1.7
*/
@Component
@ConfigurationProperties(prefix = "com.zyd")
// PropertySource application.properties
// @PropertySource(value = "config.properties")
public class PropertiesConfig {
public String type3;
public String title3;
public Map login = new HashMap();
public List urls = new ArrayList<>();
public String getType3() {
return type3;
}
public void setType3(String type3) {
this.type3 = type3;
}
public String getTitle3() {
try {
return new String(title3.getBytes("ISO-8859-1"), "UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
return title3;
}
public void setTitle3(String title3) {
this.title3 = title3;
}
public Map getLogin() {
return login;
}
public void setLogin(Map login) {
this.login = login;
}
public List getUrls() {
return urls;
}
public void setUrls(List urls) {
this.urls = urls;
}
} プログラム起動クラス:Applaction.java
package com.zyd.property;

プログラム起動クラス:Applaction.java
import java.io.UnsupportedEncodingException;

@SpringBootApplication
@RestController
public class Applaction {
@Value("${com.zyd.type}")
private String type;
@Value("${com.zyd.title}")
private String title;
/**

@RequestMapping("/value")
public Map value() throws UnsupportedEncodingException {
Map map = new HashMap();
map.put("type", type);
// *.properties ISO-8859-1 ，
map.put("title", new String(title.getBytes("ISO-8859-1"), "UTF-8"));
return map;

public static void main(String[] args) throws Exception {
SpringApplication application = new SpringApplication(Applaction.class);
application.run(args);
}
} アクセス結果:
{"title":" @Value ","type":"Springboot - @Value"}三、Environmentの使用
プログラム起動クラス:Applaction.java
package com.zyd.property;

import org.springframework.beans.factory.annotation.Autowired;

@SpringBootApplication
@RestController
public class Applaction {
@Autowired
private Environment env;
/**

* ： `Environment`
*
* @author zyd
* @throws UnsupportedEncodingException
* @since JDK 1.7
*/
@RequestMapping("/env")
public Map env() throws UnsupportedEncodingException {
Map map = new HashMap();
map.put("type", env.getProperty("com.zyd.type2"));
map.put("title", new String(env.getProperty("com.zyd.title2").getBytes("ISO-8859-1"), "UTF-8"));
return map;
}
public static void main(String[] args) throws Exception {
SpringApplication application = new SpringApplication(Applaction.class);
application.run(args);
}
} アクセス結果:
{"title":" Environment ","type":"Springboot - Environment"}四、PropertiesLoaderUtilsの使用
app-config.properties
#### (`Listeners`) + `PropertiesLoaderUtils`
com.zyd.type=Springboot - Listeners
com.zyd.title= Listeners + PropertiesLoaderUtils
com.zyd.name=zyd
com.zyd.address=Beijing
com.zyd.company=inPropertiesListener.JAvaはロードプロファイルを初期化するために使用されます
package com.zyd.property.listener;
import org.springframework.boot.context.event.ApplicationStartedEvent;
import org.springframework.context.ApplicationListener;
import com.zyd.property.config.PropertiesListenerConfig;
/**

* @since JDK ： 1.7
*/
public class PropertiesListener implements ApplicationListener<ApplicationStartedEvent> {
private String propertyFileName;
public PropertiesListener(String propertyFileName) {
this.propertyFileName = propertyFileName;
}
@Override
public void onApplicationEvent(ApplicationStartedEvent event) {
PropertiesListenerConfig.loadAllProperties(propertyFileName);
}
}PropertiesListenerConfig.JAvaプロファイルの内容のロード

private static void processProperties(Properties props) throws BeansException {

for (Object key : props.keySet()) {
String keyStr = key.toString();
try {
// PropertiesLoaderUtils ISO-8859-1,
propertiesMap.put(keyStr, new String(props.getProperty(keyStr).getBytes("ISO-8859-1"), "utf-8"));
