1.获取激活的环境值
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
@Component
public class PropertiesConstantUtil {
public static String PROFILE;
//直接用的@value 也可以通过 environment等去获取
@Value("${spring.profiles.active}")
public void setPROFILE(String profile) {
this.PROFILE = profile;
}
}
2.自定义PropertiesLoader类加载配置
import java.io.IOException;
import java.io.InputStream;
import java.util.NoSuchElementException;
import java.util.Properties;
import org.apache.commons.io.IOUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.core.io.DefaultResourceLoader;
import org.springframework.core.io.Resource;
import org.springframework.core.io.ResourceLoader;
public class PropertiesLoader {
private static Logger logger = LoggerFactory.getLogger(PropertiesLoader.class);
private static ResourceLoader resourceLoader = new DefaultResourceLoader();
private final Properties properties;
public PropertiesLoader(String... resourcesPaths) {
this.properties = this.loadProperties(resourcesPaths);
}
public Properties getProperties() {
return this.properties;
}
private String getValue(String key) {
String systemProperty = System.getProperty(key);
if (systemProperty != null) {
return systemProperty;
} else {
return this.properties.containsKey(key) ? this.properties.getProperty(key) : "";
}
}
public String getProperty(String key) {
String value = this.getValue(key);
if (value == null) {
throw new NoSuchElementException();
} else {
return value;
}
}
public String getProperty(String key, String defaultValue) {
String value = this.getValue(key);
return value != null ? value : defaultValue;
}
public Integer getInteger(String key) {
String value = this.getValue(key);
if (value == null) {
throw new NoSuchElementException();
} else {
return Integer.valueOf(value);
}
}
public Integer getInteger(String key, Integer defaultValue) {
String value = this.getValue(key);
return value != null ? Integer.valueOf(value) : defaultValue;
}
public Double getDouble(String key) {
String value = this.getValue(key);
if (value == null) {
throw new NoSuchElementException();
} else {
return Double.valueOf(value);
}
}
public Double getDouble(String key, Integer defaultValue) {
String value = this.getValue(key);
return value != null ? Double.valueOf(value) : (double)defaultValue;
}
public Boolean getBoolean(String key) {
String value = this.getValue(key);
if (value == null) {
throw new NoSuchElementException();
} else {
return Boolean.valueOf(value);
}
}
public Boolean getBoolean(String key, boolean defaultValue) {
String value = this.getValue(key);
return value != null ? Boolean.valueOf(value) : defaultValue;
}
private Properties loadProperties(String... resourcesPaths) {
Properties props = new Properties();
String[] var3 = resourcesPaths;
int var4 = resourcesPaths.length;
for(int var5 = 0; var5 < var4; ++var5) {
String location = var3[var5];
InputStream is = null;
try {
Resource resource = resourceLoader.getResource(location);
is = resource.getInputStream();
props.load(is);
} catch (IOException var12) {
logger.info("Could not load properties from path:" + location + ", " + var12.getMessage());
} finally {
IOUtils.closeQuietly(is);
}
}
return props;
}
}
3.工具类读取
import com.google.common.collect.Maps;
import tech.liveeasy.platform.common.utils.PropertiesLoader;
import java.util.Map;
public class PropertiesUtil {
private static Map<String, String> map = Maps.newHashMap();
private static PropertiesLoader loader = new PropertiesLoader(new String[]{"application.properties", "application-" + PropertiesConstantUtil.PROFILE + ".properties"});
public static String getConfig(String key) {
String value = map.get(key);
if (value == null) {
value = loader.getProperty(key);
map.put(key, value != null ? value : "");
}
return value;
}
public static Boolean isDebug() {
String debug = getConfig("web.debug");
return "true".equals(debug);
}
}
