编码过滤器： 

package com.imooc.oa.global;

import javax.servlet.*;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class EncodingFilter implements Filter {
    private String encoding = "utf-8";
    public void init(FilterConfig filterConfig) throws ServletException {
      //读取初始化参数，参数可以以encoding为建指定编码。来避免中文乱码,有了这个指定的编码就可以以他为格式。
         if(filterConfig.getInitParameter("encoding")!=null){
             encoding = filterConfig.getInitParameter("encoding");
         }
     //这一段代码是将编码个格式设置你指定的encoding如果他不为空的话 。
    }


    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
          //这里是过滤和拦截
        HttpServletRequest request = (HttpServletRequest)servletRequest;
        HttpServletResponse response = (HttpServletResponse)servletResponse;
        request.setCharacterEncoding(encoding);
        response.setCharacterEncoding(encoding);
        filterChain.doFilter(request, response); //这一段代码是拦截

    }


    public void destroy() {
        //这里是销毁
    }
}

然后是对过滤器的配置： 
子啊web-info的web.xml中

<filter>
    <filter-name>encoding</filter-name>
    <filter-class>com.imooc.oa.global.EncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>utf-8</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>encoding</filter-name>
    <url-pattern>/*</url-pattern>
    <!--/*代表的是所有的请求-->
</filter-mapping>

静态资源的复制： 

<servlet-name>default</servlet-name>
<url-pattern>/assets/*</url-pattern>
assets目录下所有的请求都交给默认的servlet来进行处理。 

<servlet-name>default</servlet-name>
<url-pattern>/assets/*</url-pattern>
<url-pattern>/js/*</url-pattern>
<url-pattern>/vendor/*</url-pattern>
<url-pattern>*.js</url-pattern>
<url-pattern>*.jpg</url-pattern>
<url-pattern>*.gif</url-pattern>
<url-pattern>*.png</url-pattern>
<url-pattern>*.css</url-pattern>

同理就是这些目录下的请求都先交给默认的servlet来进行处理，然后再交给spring-mvc来处理。

常量类： 

package com.imooc.oa.global;

import java.util.ArrayList;
import java.util.List;

public class Contant {
    //这里面全是常量
    //职务
    public static final String POST_STAFF = "员工";
    public static final String POST_FM = "部门经理";
    public static final String POST_GM = "总经理";
    public static final String POST_CASHIR = "财务";

    public List<String> getPost() {
        List<String> list = new ArrayList<String>();
        list.add(POST_STAFF);
        list.add(POST_FM);
        list.add(POST_GM);
        list.add(POST_CASHIR);
        return list;
    }

    //声明费用列别。
    public List<String> getItems() {
        List<String> list = new ArrayList<String>();
        list.add("交通");
        list.add("餐饮");
        list.add("住宿");
        list.add("办公");
        return list;
    }

    //关于报销单状态
    public static final String CLAIMVOUCHER_CREATED = "新创建";
    public static final String CLAIMVOUCHER_SUBMIT = "已提交";
    public static final String CLAIMVOUCHER_APPROVED = "已审核";
    public static final String CLAIMVOUCHER_BACK = "已打回";
    public static final String CLAIMVOUCHER_TERMINATED = "已终止";
    public static final String CLAIMVOUCHER_RECHECK = "待复审";
    public static final String CLAIMVOUCHER_PAID = "已打款";
    //审核额度
    public static final double LIMIT_CHECK=5000.00;
    //处理方式
    public static final String DEAL_CREATE = "创建";
    public static final String DEAL_SUBMIT = "提交";
    public static final String DEAL_UPDATE = "修改";
    public static final String DEAL_BACK = "打回";
    public static final String DEAL_REJECT ="拒绝";
    public static final String DEAL_PASS = "通过";
    public static final String DEAL_PAID = "打款";

}

这就是常量类，也就是数据字典。
