一、maven目录结构

官网的解释如下： http://maven.apache.org/guides/introduction/introduction-to-the-standard-directory-layout.html

Introduction to the Standard Directory Layout

Having a common directory layout would allow for users familiar with one Maven project to immediately feel at home in another Maven project. The advantages are analogous to adopting a site-wide look-and-feel.

The next section documents the directory layout expected by Maven and the directory layout created by Maven. Please try to conform to this structure as much as possible; however, if you can't these settings can be overridden via the project descriptor.

src/main/java	Application/Library sources
src/main/resources	Application/Library resources
src/main/filters	Resource filter files
src/main/webapp	Web application sources
src/test/java	Test sources
src/test/resources	Test resources
src/test/filters	Test resource filter files
src/it	Integration Tests (primarily for plugins)
src/assembly	Assembly descriptors
src/site	Site
LICENSE.txt	Project's license
NOTICE.txt	Notices and attributions required by libraries that the project depends on
README.txt	Project's readme

At the top level, files descriptive of the project: a pom.xml file. In addition, there are textual documents meant for the user to be able to read immediately on receiving the source: README.txt, LICENSE.txt, etc.

There are just two subdirectories of this structure: src and target. The only other directories that would be expected here are metadata like CVS, .git or .svn, and any subprojects in a multiproject build (each of which would be laid out as above).

The target directory is used to house all output of the build.

The src directory contains all of the source material for building the project, its site and so on. It contains a subdirectory for each type: main for the main build artifact, test for the unit test code and resources, site and so on.

Within artifact producing source directories (ie. main and test), there is one directory for the language java (under which the normal package hierarchy exists), and one for resources (the structure which is copied to the target classpath given the default resource definition).

If there are other contributing sources to the artifact build, they would be under other subdirectories: for example src/main/antlr would contain Antlr grammar definition files.

 

src/main/java  存放项目的java类源文件，即：Xxx.java

src/main/resources  存放项目的资源文件，如spring、mybatis的配置文件等等

src/test/java  存放项目的用于测试的java类源文件，即：XxxTest.java

src/test/resources  存放项目的测试相关的资源文件

 

二、访问resource路径下的文件

build后resource文件会在target/classes目录下

web.xml通过classpath:xxx.xml来访问
