javaWeb项目之新闻管理系统
这是csdn保存的源码，如有需要，可自行下载：https://download.csdn.net/download/fzt12138/11776339
另外，根据各位下载后的反馈，系统中缺少jar包，现已补齐，下载地址为：https://download.csdn.net/download/fzt12138/13206785
如有需要，可自行下载，该系统为MySQL数据库，idea开发。
关于如何导入项目，请见https://blog.csdn.net/qq_42986107/article/details/88412386

<![CDATA[
This is the XML Schema for the Servlet 2.5 deployment descriptor.
The deployment descriptor must be named "WEB-INF/web.xml" in the
web application's war file. All Servlet deployment descriptors
must indicate the web application schema by using the Java EE
namespace:
http://java.sun.com/xml/ns/javaee
and by indicating the version of the schema by
using the version element as shown below:
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="..."
version="2.5">
...
</web-app>
The instance documents may indicate the published version of
the schema using the xsi:schemaLocation attribute for Java EE
namespace with the following location:
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd
]]>
</xsd:documentation>
</xsd:annotation>
<xsd:annotation>
<xsd:documentation>
The following conventions apply to all Java EE
deployment descriptor elements unless indicated otherwise.
- In elements that specify a pathname to a file within the
same JAR file, relative filenames (i.e., those not
starting with "/") are considered relative to the root of
the JAR file's namespace. Absolute filenames (i.e., those
starting with "/") also specify names in the root of the
JAR file's namespace. In general, relative names are
preferred. The exception is .war files where absolute
names are preferred for consistency with the Servlet API.

<xsd:element name="web-app" type="javaee:web-appType">
<xsd:annotation>
<xsd:documentation>
The web-app element is the root of the deployment
descriptor for a web application. Note that the sub-elements
of this element can be in the arbitrary order. Because of
that, the multiplicity of the elements of distributable,
session-config, welcome-file-list, jsp-config, login-config,
and locale-encoding-mapping-list was changed from "?" to "*"
in this schema. However, the deployment descriptor instance
file must not contain multiple elements of session-config,
jsp-config, and login-config. When there are multiple elements of
welcome-file-list or locale-encoding-mapping-list, the container
must concatenate the element contents. The multiple occurence
of the element distributable is redundant and the container
treats that case exactly in the same way when there is only
one distributable.

The load-on-startup element indicates that this

The transport-guaranteeType specifies that the communication

that the application requires that the data sent between the

changed in transit. CONFIDENTIAL means that the application
requires that the data be transmitted in a fashion that
prevents other entities from observing the contents of the

required.
