配置編碼

在oa-web  com.imooc.oa.global中創建EncodingFilter.java

package com.imooc.oa.global;

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

public class EncodingFilter implements Filter {
    private String encoding="utf-8";
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        if(filterConfig.getInitParameter("encoding")!=null){
            encoding = filterConfig.getInitParameter("encoding");
        }
    }

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
        HttpServletRequest request = (HttpServletRequest)servletRequest;
        HttpServletResponse response = (HttpServletResponse)servletResponse;
        request.setCharacterEncoding(encoding);
        response.setCharacterEncoding(encoding);
        filterChain.doFilter(request,response);
    }

    @Override
    public void destroy() {

    }
}

在oa-web 的web.xml中插入

  <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>
  </filter-mapping>

導入靜態資源

在web.xml中加入

  <servlet-mapping>
    <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>
  </servlet-mapping>

創建常量類

在oa-dao的com.imooc.oa.global中創建Contant類

package com.imooc.oa.global;

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

public class Contant {
    //職務
    public static final String POST_STAFF="員工";
    public static final String POST_FM="部門經理";
    public static final String POST_GM="總經理";
    public static final String POST_CASHIER="財務";
    public static List<String> getPosts(){
        List<String> list = new ArrayList<String>();
        list.add(POST_STAFF);
        list.add(POST_FM);
        list.add(POST_GM);
        list.add(POST_CASHIER);
        return list;
    }

    //費用類別
    public static List<String> getItems(){
        List<String> list = new ArrayList<String>();
        list.add("交通");
        list.add("餐飲");
        list.add("住宿");
        list.add("辦公");
        return list;
    }

    //報銷單狀態
    public static final String CLAIMVOUCHER_CREATED="新創建";
    public static final String CLAIMVOUCHER_SUBMIT="已提交";
    public static final String CLAIMVOUCHER_APPROVED="已審覈";
    public static final String CLAIMVOUCHER_BACK="已打回";
    public static final String CLAIMVOUCHER_TERMINATED="已終止";
    public static final String CLAIMVOUCHER_RECHECK="待複審";
    public static final String CLAIMVOUCHER_PAID="已打款";
    //審覈額度
    public static final double LIMIT_CHECK=5000.00;

    //處理方式
    public static final String DEAL_CREATE="創建";
    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="拒絕";

    public static final String DEAL_PAID="打款";
}
