java程序调用CMD命令启动tomcat替换环境变量

出现问题：

　　此时不应有 files\java\jdk1.8.0_92\bin\java.exe""（本地未出现问题，服务器环境出现）

 

出现原因：

　　1：环境变量java_home配置路径中的空格问题

2：系统环境变量路径首尾出现双引号  " 为多余

解决方法：

　　1：原路径c:\program files\java\jdk1.8.0_92，需替换为c:\progra~1\java\jdk1.8.0_92 ；

　　2：将相关环境变量路径的首尾双引号 “  去掉 ；

如：

import java.util.concurrent.future;

env.put("catalina_home", file.getparent());

env.put("catalina_base", file.getparent());

logger.info("=: -----------------------");

for(string str : env.keyset()){

if(env.get(str) != null){

　　env.put(str, env.get(str).replaceall("program files", "progra~1"));

}

logger.info(str+"=: "+env.get(str));

}

logger.info("=: -----------------------");

string javahome = system.getenv("java_home");

if(stringutils.isnotempty(javahome)) {

javahome = javahome.replace("%20", " ").replaceall("program files", "progra~1");

}

env.put("java_home", javahome);

//环境可能是path 或  path

string _path = env.get("path");

if(stringutils.isnotempty(_path)){

env.put("path", _path.replaceall("\"", ""));

}

string _path = env.get("path");

}

string _execjava = env.get("_execjava");

if(stringutils.isnotempty(_execjava)){

}

}
