如何在 Tomcat 中启用 Java 断言 [英] How can I enable java assertions in Tomcat
问题描述
我想在我的 Spring web 应用程序中使用 Java assert
关键字,主要是在我的域类上(检查构造函数中的不变量),但我看不到如何启用运行时断言检查.
I would like to use the Java assert
keyword in my Spring web-app, primarily on my domain classes (checking invariants within constructors), but I cannot see how to enable runtime assertion checking.
对于普通的 java 应用程序,我会在 java 命令中使用 -ea
开关,但我不知道如何使用 Tomcat 等来做到这一点.
For a normal java application, I would use the -ea
switch with the java command, but I don't see how I can do that with Tomcat, etc.
这是推荐的东西,还是我应该使用 Spring 框架中的Assert"类?然而,我宁愿让我的域类不受 Spring 依赖.
Is this the recommended thing, or should I use the "Assert" class from the Spring framework? I'd rather keep my domain classes free of Spring dependencies, however.
推荐答案
对于tomcat,在JAVA_OPTS
中添加-ea
(所有java进程都启动了),甚至更好CATALINA_OPTS
(仅适用于网络应用引擎).
For tomcat, add -ea
to JAVA_OPTS
(all java processes started), or even better to CATALINA_OPTS
(only to web app engine).
阅读文件 catalina.bat
或 catalina.sh
以获取有关 JAVA_OPTS
和 CATALINA_OPTS
的更多信息.
Read the files catalina.bat
or catalina.sh
for more information on JAVA_OPTS
and CATALINA_OPTS
.
