Question

我的系统上安装了四个JDK用于多个模块。

jdk1.8.0_25， jdk1.7.0_75和 jdk1.6.0_19

我想配置或更改Mule.bat，以便它应该选择与Java home中设置的Java版本不同的默认Java版本。

以下是Mule.bat的代码，但我无法在其中找到Java Home参数。

Answer 1

Mule使用Java Service Wrapper从您的本机操作系统控制Java虚拟机（JVM）。

1）您需要对wrapper.conf文件进行更改： -

$ MULE_HOME / CONF / wrapper.conf

2）然后你需要在其中设置 wrapper.java.command 参数，

wrapper.java.command =％JAVA_HOME％/ bin中/ JAVA

或

wrapper.java.command = C：/jdk1.6.0/bin/java

JAVA_HOME

Answer 2

如果在console.log(typeof myNamespace); // object脚本中找不到Java Home，则很可能是因为Mule.bat脚本要么直接使用计算机上定义的属性Mule.bat，要么使用第一个JAVA_HOME，java。{/ 1}}

如果你想这样做，我建议你不要直接修改PATH脚本，而是创建另一个脚本，在Mule.bat修改后调用Mule.bat。

这样您就不会依赖JAVA_HOME脚本（例如，在Mulesoft版本升级的情况下）。

如何使用不同的Java版本配置Mule ESB（mule.bat）？
