spring4.3.1 mvc部署试验

才接触spring mvc不久,对他的超强的便捷功能赞叹不已,自己也试着做了一个部署试验,记录在此.以便日后查阅校准.

环境:

jdk1.7

spring mvc 4.3.1

db2

1,web.xml

首先需要在web.xml里对spring进行设置,如下

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>

2.在web.xml中设置的spring-servlet.xml中对spring进行详细设置

</pre><pre>

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation=" http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

<context:component-scan base-package="jp.spring.test" />

<!-- don't handle the static resource -->
<mvc:default-servlet-handler />

<!-- if you use annotation you must configure following setting -->
<mvc:annotation-driven />

<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.ibm.db2.jcc.DB2Driver"></property>
<property name="url" value="jdbc:db2://localhost:50000/SPRDB"></property>
<property name="username" value="db2admin"></property>
<property name="password" value="db2admin"></property>
</bean>
<span style="white-space:pre"> </span><pre name="code" class="html"><span style="white-space:pre"> </span><!-- spring mvc的jdbc封装组件定义 -->
<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate"><property name="dataSource" ref="dataSource" /></bean>
<span style="white-space:pre"> </span><!-- 调用jdbc封装组件的daoImpl定义 -->
<bean id="userLoginDao" class="jp.spring.test.dao.impl.UserLoginDaoImpl"><property name="jdbcTemplate" ref="jdbcTemplate" /></bean></beans>

3,导入所需要的架包



4,spring mvc 开发(用户登录)



4-1,dao

package jp.spring.test.dao;

import java.util.List;

import jp.spring.test.domain.User;

public interface UserLoginDao {
public List<User> getUserInfo(User user);

public List<User> getUserByName(String name);
}

package jp.spring.test.dao.impl;

import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.RowMapper;

import jp.spring.test.dao.UserLoginDao;
import jp.spring.test.domain.User;

public class UserLoginDaoImpl implements UserLoginDao {

private JdbcTemplate jdbcTemplate;
@Autowired
public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
this.jdbcTemplate = jdbcTemplate;
}

@Override
public List<User> getUserInfo(User user) {

String sql = "SELECT * FROM LOGIN_INFO WHERE USER_NAME=? AND USER_PASSWORD=?";
String name = user.getName();
String password = user.getPassword();
List<User> list = jdbcTemplate.query(sql, new MyResult(), name, password);
return list;
}

@Override
public List<User> getUserByName(String name) {
String sql = "SELECT * FROM LOGIN_INFO WHERE USER_NAME=? ";
List<User> list = jdbcTemplate.query(sql, new MyResult(), name);
return list;
}

}
//从数据库直接返回对象
class MyResult implements RowMapper<User> {
@Override
public User mapRow(ResultSet rs, int index) throws SQLException {
User user = new User();
user.setName(rs.getString("USER_NAME"));
user.setPassword(rs.getString("USER_PASSWORD"));
return user;
}
}

4-2,service

package jp.spring.test.service;
import java.util.List;

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

import jp.spring.test.dao.UserLoginDao;
import jp.spring.test.domain.User;
@Service
public class Webservice {
@Autowired
private UserLoginDao userLoginDao;

public List<User> checkLogin(User user){
List<User> list = userLoginDao.getUserInfo(user);
return list;
}
public List<User> checkRegister(String name){
return null;
}
}

4-3,controller

package jp.spring.test.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;

import jp.spring.test.domain.User;
import jp.spring.test.service.Webservice;

@Controller
@RequestMapping("/zhangjie")
public class WebController {
@Autowired
private Webservice webservice;

@RequestMapping("hello")
public String tohelloPage(){
return "hello";
}

@RequestMapping(value="loginCheck",params="login",method=RequestMethod.POST)
public String userLogin(@RequestParam("name") String name,
@RequestParam("password") String password,
Model model) {
String veiwId=null;
User user=new User();
user.setName(name);
user.setPassword(password);
List<User> list = webservice.checkLogin(user);
if(list.size()<1){
veiwId="hello";
model.addAttribute("loginFail","ユーザー名かパスポートか間違いました");
}else{
veiwId="index";
model.addAttribute("loginSuccess","ようこそ、いっラシャいませ");
model.addAttribute("userName",list.get(0).getName());
}
return veiwId;
}
@RequestMapping(value="loginCheck",params="register",method=RequestMethod.POST)
public String userRegister() {
return "register";
}
@RequestMapping(value="register",params="register",method=RequestMethod.POST)
public String userregister(@RequestParam("name") String name,
@RequestParam("password") String password,
@RequestParam("sex") String sex,
@RequestParam("age") String age,
Model model) {
String viewId=null;
List<User> list = webservice.checkRegister(name);
if(list.size()<1){
viewId="register";
model.addAttribute("loginFail","ユーザー名かパスポートか間違いました");
}else{
viewId="index";
model.addAttribute("loginSuccess",
4000
"ようこそ、いっラシャいませ");
model.addAttribute("userName",list.get(0).getName());
}
return viewId;
}
}

4-4,domain

package jp.spring.test.domain;

import org.springframework.stereotype.Component;

@Component
public class User {
private String name;
private String password;
private String age;
private String sex;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
@Override
public String toString() {
return "user [name=" + name + ", password=" + password + ", age=" + age + ", sex=" + sex + "]";
}
}

4-5,jsp

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<form action="loginCheck" method="post">
<div>hello ,this is a spring mvc demo!!</div>

<table>
<tr>
<th>login</th>
</tr>
<tr>
<td>name:</td><td><input type="text" name="name" value="" ></td>
</tr>
<tr>
<td>password:</td><td><input type="password" name="password" value="" ></td>
</tr>
<tr>
<td ><input type="submit" id="login" name="login" value="login"></td>
<td ><input type="submit" id="register" name="register" value="register"></td>
</tr>
</table>
<div><h3><c:if test="${!empty loginFail }">${loginFail}</c:if></h3></div>
</form>
</body>
</html>

试验中,出现多次spring启动报错情况,集中在db2的jdbc引用方面

<pre name="code" class="html"><property name="driverClassName" value="com.ibm.db2.jcc.DB2Driver"></property>

排查中发现没有导入db2jcc4.jar与db2jcclicensecu.jar两个包,导入后启动正常.
