我们将spring项目从3.2.3迁移到4.2.3。请注意，由于缺少上下文路径，我们正面临404问题，它与3.2.3一起运行良好。
<form:form action="/planning/plan"> - current snippet in 3.2.3.Release
but after migration it is expecting contextpath as prefix like below
<form:form action="testabc/planning/plan"> testabc is context path
什么问题可以请任何人建议是什么原因 下面是我们正在使用的罐子列表，我们真正需要添加上下文路径的问题是什么
