1. The proxy of eclipse is set, but the availability of this proxy is not very good, or there is a problem. However, when eclipse starts to judge whether tomcat is started or not, it actually accesses the virtual machine of tomcat through the network, and then accesses it through the proxy. This It has been connected since then, resulting in the state that tomcat has been started all the time. The solution is to cancel the use of the eclipse proxy . The specific reason remains to be studied in detail.
2. Set up a network proxy, the same problem after modifying the registry , the solution is to cancel the use of the proxy
3. Quoting a comment from "zhangyou1010"
My eclipse is not set up proxy, also have this problem.
