Question

Answer 1

您没有给我们太多帮助，但根据您的问题，我怀疑您忘记更新您的String参考。它就像这样简单，

String str = "ws([WM_10003] , {MD_1402359631813}{MV_200101010000024})";
String toRemove = "{MD_1402359631813}";
System.out.println("Before: " + str);
str = str.replace(toRemove, "");
System.out.println("After: " + str);

输出

Before: ws([WM_10003] , {MD_1402359631813}{MV_200101010000024})
After: ws([WM_10003] , {MV_200101010000024})
