Classpathxmlapplicationcontext and Filesystemxmlapplicationcontext path issues

Classpathxmlapplicationcontext Problems in 1.Spring

Classpathxmlapplicationcontext is loading the corresponding XML file from the Classpath class load path.

(1) Generally use classpath path, prefix can be added without adding,

Example: New Classpathxmlapplicationcontext ("Classpath:conf/core/train-servlet.xml")

(2) You can also use absolute path, plus file: Absolute path, generally not recommended absolute path

2. Filesystemxmlapplicationcontext:

(1) using the path of the file system, the default specifies the root path of the project, SRC

Example: New Filesystemxmlapplicationcontext ("Src/conf/core/train-servlet.xml")

(2) You can also use the classpath path so that you can read the relative path below the classpath,

Example: New Filesystemxmlapplicationcontext ("Classpath:conf/core/train-servlet.xml")

(3) No need to add File: prefix denotes absolute path, do not advocate use

1. No drive letter is the project work path, that is, the root directory of the project; Src

2. A drive symbol indicates the absolute path of the file. D:\test\ Error Problem:

Noclassdeffounderror The reason is that the corresponding class is not found and the corresponding bean in the Spring.xml file is configured incorrectly.
