前置準備
1、java虛擬機
2雾棺、eclipse
3膊夹、tomcat
4、hbuilder
5捌浩、mysql+navicat
6割疾、maven與eclipse集成
運行時效果圖

新建maven項目
1)file-new -maven project
2)接下來的頁面里勾選 create a simple project
3)下一個頁面設置項目名，包名嘉栓，項目類型
4）問題及解決
導致上面錯誤的原因是沒有自動生成web.xml
解決方法：
進入到project 視圖做如下操作
成功后生成了web.xml
maven下載依賴jar包
pom.xml中新增加如下依賴

下jar包
新建包
com.neusoft.utils 工具類
com.neusoft.filter 放置編碼過濾器，解決中文亂碼問題
com.neusoft.servlet servlet(Controller層)
com.neusoft.service service
com.neusoft.dao
com.neusoft.pojo 實體類
過濾器代碼
前置確認倍谜，確認項目為servlet3.0
com.neusoft.filter 包右鍵-new-filter
問題及解決：
問題原因是filter在tomcat里迈螟，把tomcat引進來即可
過濾器關鍵代碼
@WebFilter(filterName = "EncodingFilter" , urlPatterns = "/*")
public class EncodingFilter implements Filter {
/**
* Default constructor.
*/
public EncodingFilter() {
// TODO Auto-generated constructor stub
}
/**
* @see Filter#destroy()
*/
public void destroy() {
// TODO Auto-generated method stub
}
/**
* @see Filter#doFilter(ServletRequest, ServletResponse, FilterChain)
*/
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
// TODO Auto-generated method stub
// place your code here
// pass the request along the filter chain
chain.doFilter(request, response);
}
/**
* @see Filter#init(FilterConfig)
*/
public void init(FilterConfig fConfig) throws ServletException {
// TODO Auto-generated method stub
}
}
以后中文就不會亂碼了，哈哈
實體類編寫
用于持久化時包裝數(shù)據(jù)尔崔，方便后續(xù)開發(fā)
com.neusoft.pojo.HealthCode
public class HealthCode {
private Integer id;
private String name ;
private String imgUrl ;
private String telephone ;
private String idcard ;
private String location ;
private String carNo ;
private String tmpLocation ;
private String outToIn ;
private String sex ;
private String health ;
private String cardColor ;
private Date createTime ;
..自動生成get/set
}
