仅供参考-接上文

springmvc

1.设置Log4jConfigListener日志监听(可以为开发调试、发布后运行的意外调试、等)

　　在src/main/resources目录下新建log4j.properties文件(可以在别的目录)，这些配置内容网上有很多，

# This is the configuring for logging displayed in the Application Server

log4j.rootCategory=error, stdout, logfile

#log4j.rootCategory=debug, stdout, logfile

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%d %5p (%F:%L) - %m%n

log4j.logger.org.springframework=WARN

log4j.logger.org.mybatis.SQL=DEBUG

log4j.logger.org.springframework.transaction=WARN

log4j.logger.org.springframework.orm=WARN

log4j.logger.com.google.code.yanf4j=WARN

log4j.logger.net.rubyeye.xmemcached=WARN

log4j.logger.org.mybatis.spring=WARN

log4j.logger.org.apache.activemq=WARN

log4j.logger.providers.XmlConfigurationProvider=WARN

#log4j.logger.org.springframework.web.servlet.DispatcherServlet=WARN

#log4j.logger.org.acegisecurity=INFO

#log4j.logger.org.springframework.web.servlet.handler=INFO

#### First appender writes to console

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%-4p,%t,%d{MM-dd HH:mm:ss.SSS},%c{2}.%M:%L - %m%n

log4j.appender.logfile=org.apache.log4j.RollingFileAppender

log4j.appender.logfile.File=${catalina.base}/logs/ecms.log

log4j.appender.logfile.MaxFileSize=1024KB

# Keep 9 backup files.

log4j.appender.logfile.MaxBackupIndex=9

# Pattern to output: date priority [category] - message

log4j.appender.logfile.layout=org.apache.log4j.PatternLayout

log4j.appender.logfile.layout.ConversionPattern=%d %t %p [%c] - %m%n

log4j.logger.com.ibatis=debug

log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=debug

log4j.logger.com.ibatis.common.jdbc.ScriptRunner=debug

log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=debug

log4j.logger.java.sql.Connection=debug

log4j.logger.java.sql.Statement=debug

log4j.logger.java.sql.PreparedStatement=debug,stdout

　　在web.xml文件中配置一下

<!-- 日志  -->

      <listener>

        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>

    </listener>

    <context-param>

        <param-name>log4jConfigLocation</param-name>

        <!-- 这里对应的配置文件目录  -->

        <param-value>classpath:log4j.properties</param-value>

    </context-param>

    <context-param>

        <param-name>webAppRootKey</param-name>

        <param-value>webName.root</param-value>

    </context-param>

    <!-- 开一条watchdog线程每6秒扫描一下配置文件的变化  -->

    <context-param>

        <param-name>log4jRefreshInterval</param-name>

        <param-value>60000</param-value>

    </context-param>

　　这样配置好了，可以启动一下工程登入，看看控制台是否输出sql等

2.过滤器filter(设置路径，方便前台获取)在com.springmvc.util.action包下新建SetCharacterEncodingFilter类实现Filter

package com.springmvc.util.action;

import java.io.IOException;

import javax.servlet.Filter;

import javax.servlet.FilterChain;

import javax.servlet.FilterConfig;

import javax.servlet.ServletException;

import javax.servlet.ServletRequest;

import javax.servlet.ServletResponse;

/**

 * 过滤器

 * @author

 *

 */

public class SetCharacterEncodingFilter implements Filter{

    @Override

    public void destroy() {

    }

    @Override

    public void doFilter(ServletRequest arg0, ServletResponse arg1,

            FilterChain arg2) throws IOException, ServletException {

        String path = arg0.getServletContext().getContextPath();

        String basePath = arg0.getScheme()+"://"+arg0.getServerName()+":"+arg0.getServerPort()+path+"/";

        arg0.setAttribute("basePath", basePath);//设置url路径

        arg2.doFilter(arg0, arg1);//通过

    }

    @Override

    public void init(FilterConfig arg0) throws ServletException {

    }

}

SetCharacterEncodingFilter

　　可以在实现方法中设置很多内容，例如：日志、权限、安全等内容，在doFilter方法中，获取工程路径，设置一下在页面方便获取

　　在web.xml设置，之前搭建项目是使用过filter，定义编码

<!--配置过滤器-->

    <filter>

    <!--过滤器名称，随便定义-->

            <filter-name>UrlFilter</filter-name>

    <!--filter-class指向自定义的过滤器，完整的包名+类名-->

            <filter-class>

                com.springmvc.util.action.SetCharacterEncodingFilter

            </filter-class>

    <!--过滤器中的默认参数，默认的字符编码是UTF-8-->

            <init-param>

                <param-name>defaultEncoding</param-name>

                <param-value>UTF-8</param-value>

            </init-param>

    </filter>

    <!--filter和filter-mapping是成对出现的-->

        <filter-mapping>

    <!--过滤器名称，一定要和上面的一样，-->

            <filter-name>UrlFilter</filter-name>

    <!--表示拦截所有的请求-->

            <url-pattern>/*</url-pattern>

        </filter-mapping>

　　这样可以在页面获取绝对路径了

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

页面

var loginFunction={

        //登入

        loginSubmit : function(){

            var email = $("#login-email").val();//邮箱

            var password = $("#login-password").val();//密码

            if(email =="") {

                alert("请输入邮箱");

                return;

            }

            if(password =="") {

                alert("请输入密码");

                return;

            }

            //$("#login").attr("action",basePath+"index.htm");

            //$("#login").submit();

            $.ajax({

                url: basePath+"101/loginCheck.htm",

                type:"post",

                data:{email : email,password:password},//密码得加密

                dataType:"json",

                success: function(data){

                    if(data.status == "success"){

                        window.location.href = basePath+"101/index.htm";

                    }else{

                        alert("用户名或密码错误");

                    }

                },

                error : function(data) {

                }

            });

        }

};

$(function(){

});

　　可以在公共页面这样设置，在引用js中可以使用

<script type="text/javascript">

    var basePath = "${basePath}";

</script>

3.根据项目需求，设置一些公共类，可以设置一些类继承，这样相对来说就规范和方便一些

　　在com.springmvc.util.model包下简单设置两个类HttpStatus.java、Response.java

package com.springmvc.util.model;

public class HttpStatus {

    public final static String HTTP_SUCCESS = "success"; // 操作成功

    public final static String HTTP_ERROR = "error"; // 操作失败

    public final static String HTTP_500 = "500"; // 服务器内部错误

}

HttpStatus.java

package com.springmvc.util.model;

import java.util.HashMap;

import java.util.Map;

public class Response {

    private String status;

    private String message;

    private Map<String, Object> parameter;

    public void addAttribute(String key, Object value) {

        if (parameter == null) {

            parameter = new HashMap<String, Object>();

        }

        parameter.put(key, value);

    }

    public void setStatusAndMessage(String status, String message) {

        this.status = status;

        this.message = message;

    }

    public void setSuccess(String message) {

        this.status = HttpStatus.HTTP_SUCCESS;

        this.message = message;

    }

    public String getStatus() {

        return status;

    }

    public void setStatus(String status) {

        this.status = status;

    }

    public String getMessage() {

        return message;

    }

    public void setMessage(String message) {

        this.message = message;

    }

    public Map<String, Object> getParameter() {

        return parameter;

    }

    public void setParameter(Map<String, Object> parameter) {

        this.parameter = parameter;

    }

}

Response.java

　　在com.springmvc.util.action包中新建BaseAction.java类，所有action都可以继承BaseAction.java，在这里设置request、response、session等

　　在这个类中使用@ModelAttribute注解

package com.springmvc.util.action;

import java.util.List;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import javax.servlet.http.HttpSession;

import org.apache.commons.collections.CollectionUtils;

import org.springframework.util.StringUtils;

import org.springframework.web.bind.annotation.ModelAttribute;

import com.springmvc.util.model.Response;

public class BaseAction{

    public Response responseUtil;

    private HttpServletRequest request;

    private HttpServletResponse response;

    private HttpSession session;

    /**

     * 验证一个值是否为空值

     *

     * @param str

     * @return

     */

    public boolean isEmpty(Object str) {

        return StringUtils.isEmpty(str);

    }

    public boolean isEmpty(List<?> list) {

        if (list == null)

            return true;

        if (CollectionUtils.isEmpty(list))

            return true;

        return false;

    }

    @ModelAttribute

    public void setReqAndRes(HttpServletRequest request, HttpServletResponse response){

        this.request = request;

        this.response = response;

        this.session = request.getSession();

    }

    public HttpServletRequest getRequest() {

         return this.request;

    }

     public HttpServletResponse getResponse() {

         return this.response;

     }

     public HttpSession getSession() {

         return this.session;

     }

}

package com.springmvc.action;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.ResponseBody;

import com.springmvc.model.User;

import com.springmvc.service.UserService;

import com.springmvc.util.action.BaseAction;

import com.springmvc.util.model.HttpStatus;

import com.springmvc.util.model.Response;

@Controller

@RequestMapping(value = "/101")

public class IndexAction extends BaseAction {

    @Autowired

    private UserService userService;

    /**

     * 首页

     *

     * @return

     */

    @RequestMapping(value = "/index.htm")

    public String index() {

        return "index";

    }

    /**

     * 登入页面

     *

     * @return

     */

    @RequestMapping(value = "/login.htm")

    public String login() {

        return "login";

    }

    /**

     * 登入验证

     *

     * @return

     */

    @RequestMapping(value = "/loginCheck.htm", method = RequestMethod.POST)

    @ResponseBody

    public Response loginCheck(User user) {

        responseUtil = new Response();

        List<User> list = userService.getUser(user);

        if (list != null && list.size() > 0) {

            responseUtil.setStatusAndMessage(HttpStatus.HTTP_SUCCESS, "验证成功");

        }

        return responseUtil;

    }

}
