springsecurity maven 打包后，404错误。maven 打包后，加载内置的xml文件

404错误，解决的办法，主要是pom文件

    <build>

        <resources>
            <resource>
                <directory>src/main/resources</directory>
               <!--包含antisamy.xml-->
                <includes>
<!--                    <include>**/*.properties</include>-->
<!--                    <include>**/*.xml</include>-->
<!--                    <include>**/*.yml</include>-->
                    <include>**/**</include>
                </includes>
                <filtering>false</filtering>
            </resource>
<!--这段解决maven package后，找不到页面，404 错误-->
            <resource>
                <directory>src/main/webapp</directory>
                <targetPath>META-INF/resources</targetPath>
                <includes>
                    <include>**/**</include>
                </includes>
            </resource>

加载内置的xml文件

antisamy-tralin.xml 文件在resources目录下，打jar包后，需要得到他的url，然后从url读取到目标中。

public class XssRequestWrapper extends HttpServletRequestWrapper {
    //获得antisamy框架所需的决策文件路径
    private static URL antisayPath = XssRequestWrapper.class.getClassLoader().getResource("antisamy-tralin.xml");
    public XssRequestWrapper(HttpServletRequest request) {
        super(request);
    }
    public static Policy policy = null;
    static {
        try {
            //过滤策略对象
            policy = Policy.getInstance(antisayPath);
        } catch (PolicyException e) {
            e.printStackTrace();
        }
    }

错误的代码,如下，这里得不到file，如果需要得到file，用上面的方法，File file = new File(url)； 构建一个。

String file = XssRequestWrapper.class.getClassLoader().getResource("antisamy-tralin.xml").getFile();
