1、各環境修改tomcat目錄下配置文件進行配置java
經過修改catalina.sh配置(TOMCAT_HOME/bin)git
進入catalina.sh找到web
JAVA_OPTS='-Xms512m -Xmx512m -XX:PermSize=256M -XX:MaxNewSize=256m -XX:MaxPermSize=512m -Dfile.encoding=UTF-8'apache
JAVA_OPTS的值插入如下語句tomcat
在後面加上 -Dglobal.config.path=/usr/local/jconfigapp
紅色字體根據配置文件所在的位置修改webapp
《後臺開發人員》本地經過idea啓動包時,須要添加如下配置maven
使用idea的maven啓動,須要在edit configurations -Runner中添加Environment variables:global.config.path=E:/maps-jushi/project-setting/dev;ide
紅色字體修改成項目路徑,如圖字體
以上方法不行,則採用如下方法:
在parameters的command line內增長「-Dglobal.config.path=E:\gitworkplace\maps-jushi\project-setting」
clean -Pdev tomcat7:run -Dmaven.tomcat.port=8081 -Dglobal.config.path=E:\gitworkplace\maps-jushi\project-setting
2、java的文件SystemProperties寫法
package com.zdnst.common.infra.utils; import java.util.Properties; /** * 讀取web.properties配置文件 * @author zhongyq * @version 1.0.0, 2013-3-19 */ public class SystemProperties { // the properties object private static Properties props; /** * This method returns the property values, if found. It loads the properties * from the map properties file if not already loaded. * @param property the property whose value is requested for * @param def the default value to return if property not found * @return String retVal the value returned */ public static String getProperty(String property, String def) { String retVal = null; getProperties(); if(props != null) retVal = props.getProperty(property, def).trim(); else retVal = def; return retVal; } /** * @describe: 根據給定的KEY獲取配置信息,沒有默認返回空字符串 * @param key * @return * @author:kui.he * @time:2014年9月22日下午12:04:25 */ public static String getProperty(String key){ return getProperty(key,""); } /** * sets the property for the given key & value * @param strKey String Key * @param strValue String Value * @return void * **/ public static void setProperty(String strKey, String strValue) { if(props != null) props.setProperty(strKey, strValue); } /** * This method loads the properties object and returns it. * @return Properties the loaded property object, else null */ public static Properties getProperties() { if(props == null) { try { loadProperties("resources.properties"); } catch(Exception exc) { System.err.println(exc.getMessage()); props = null; } } return props; } /** * This method loads the Properties object from the Map Properties file * @param file the configuration file */ public static void loadProperties(String file) throws Exception { props = loadPropertiesFile(file); } /** * This method loads a Properties object and returns it * @param file the configuration file to load */ public static Properties loadPropertiesFile(String file) throws Exception { // String proFile = ConfigUtils.getInstance().getClassPath()+file; String path = System.getProperty("global.config.path") == null ? ConfigUtils.getInstance().getClassPath() : System.getProperty("global.config.path") ; String proFile = path +"/"+file; //System.out.println(proFile); return ConfigUtils.loadProperties(proFile); // Properties retVal = new Properties(); // String url=SystemProperties.class.getClassLoader().getResource("/")+file; // System.out.println("url:"+url); // InputStream in = SystemProperties.class.getClassLoader().getResourceAsStream(file); // if(in != null) // retVal.load(in); // in.close(); // return retVal; } /** * 返回類目錄路徑,如:D:\tools\apache-tomcat-7.0.42\webapps\maps1.1\WEB-INF\classes\ * * @return * @author:kaiqiang.wu * @time:2015年11月18日上午10:59:22 */ public static String getClassPath(){ return SystemProperties.class.getClassLoader().getResource("").getPath(); } public static void main(String[] args) { System.out.println(SystemProperties.getClassPath()); } }
3、application-context.xml
<context:property-placeholder location="file:${global.config.path}/resources.properties"/>
4、將配置文件拉取到相應位置:
usr/local/jconfig/resources.properties拉取配置文件到相應的路徑;
