回答1:
Just try with this approach. add this code block in your spring boot application.
your war file must be placed in a src/main/resources directory.
@Bean
public EmbeddedServletContainerFactory servletContainerFactory() {
return new TomcatEmbeddedServletContainerFactory() {
@Override
protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(Tomcat tomcat) {
new File(tomcat.getServer().getCatalinaBase(), "webapps").mkdirs();
try {
tomcat.addWebapp("/cms", new ClassPathResource("cms.war").getFile().toString());
} catch (Exception ex) {
throw new IllegalStateException("Failed to add webapp",ex);
}
return super.getTomcatEmbeddedServletContainer(tomcat);
}
};
}
-> change the base directory in the application.properties as
server.tomcat.basedir=temp-server

A few classes have changed in Spring Boot 2 and hence you'll have to do:
@Bean
public ServletWebServerFactory servletContainer() {
return new TomcatServletWebServerFactory() {
protected TomcatWebServer getTomcatWebServer(Tomcat tomcat) {
new File(tomcat.getServer().getCatalinaBase(), "webapps").mkdirs();
try {
tomcat.addWebapp("/cms", new ClassPathResource("cms.war").getFile().toString());
} catch (Exception ex) {
throw new IllegalStateException("Failed to add webapp", ex);
}
return super.getTomcatWebServer(tomcat);
}
};
}
