Build an SSH project with maven (Spring+springmvc+hibernate)

This article introduces the use of Eclipse+maven to build the spring+springmvc+hibernate project, to log in as an example:
1. Create a MAVEN project
2. Change Maven project to dynamic website
3, Build Spring+springmvc+hibernate project 1 Create MAVEN projects Click to view: http://blog.csdn.net/tiandixuanwuliang/article/ Details/79250504#t0 2 The MAVEN project into a dynamic web site

The project diagram is as follows:
3 start to build Spring+springmvc+hibernate project 3.1 Configure Maven dependency, write the following in Pom.xml:

<project xmlns= "http://maven.apache.org/POM/4.0.0" xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xsi: schemalocation= "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" > < Modelversion>4.0.0</modelversion> <groupId>com.welljoint</groupId> <artifactId>

3.2 Please check that maven dependencies are imported into the project.Please click to view: HTTP://BLOG.CSDN.NET/TIANDIXUANWULIANG/ARTICLE/DETAILS/79250504#T4 3.3 Create a new com.welljoint.entity package in Src/main/java; Create a new User.java bean in this bag.

Package com.welljoint.entity;
/** * 
 @version  
 * @time 2018-2-28 pm 6:02:03 
 * @describe: User's Bean */public
class User {
    private Integer ID;
    Private String userName;
    private String password;

    Public Integer getId () {
        return ID;
    }
    public void SetId (Integer id) {
        this.id = ID;
    }
    Public String GetUserName () {
        return userName;
    }
    public void Setusername (String userName) {
        this.username = userName;
    }
    Public String GetPassword () {
        return password;
    }
    public void SetPassword (String password) {
        this.password = password;
    }

    @Override public
    String toString () {
        return "User [id=" + ID + ", username=" + UserName + ", password="
                + P Assword + "]";
    }
}

3.4 Create a View folder in the Web-inf directory, and create a login.jsp in the folder with the following code:

<%@ page language= "java" contenttype= "text/html; Charset=utf-8 "
    pageencoding=" UTF-8 "%>
<! DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en" "Http://www.w3.org/TR/html4/loose.dtd" >
Then create a login_success.jsp page under the View folder with the following code:
<%@ page language= "java" contenttype= "text/html; Charset=utf-8 "
    pageencoding=" UTF-8 "%>
<! DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en" "Http://www.w3.org/TR/html4/loose.dtd" >
 
3.5 Create a new com.welljoint.rest package in Src/main/java; Create a new Logincontroller.java in this package as a controller 
Package com.welljoint.rest;

Import Org.springframework.stereotype.Controller;
Import org.springframework.web.bind.annotation.RequestMapping;
Import Org.springframework.web.bind.annotation.RequestMethod;

Import Com.welljoint.entity.User;

/** * 
 @version  
 * @time 2018-2-28 pm 5:57:07 
 * @describe: Controller
 *  /@Controller//Note for controller
@ Requestmapping (value= "/login")    //Intercept request with/login public
class Logincontroller {

    @RequestMapping ( method=requestmethod.get) Public
    String GET () {  //used to return a page
        "login";  Returns a pointer to the login.jsp page
    }

    @RequestMapping (method=requestmethod.post) public
    String POST (user user) {  //To process the user's login request
        return "login_success";
    }
}
 
3.6 Create a new Spring-mvc.xml file in src/main/resources with the following code: 
<?xml version= "1.0" encoding= "UTF-8"?> <beans xmlns= "Http://www.springframework.org/schema/beans" Xmlns:xs I= "Http://www.w3.org/2001/XMLSchema-instance" xmlns:p= "http://www.springframework.org/schema/p" xmlns:context= "H Ttp://www.springframework.org/schema/context "xmlns:mvc=" Http://www.springframework.org/schema/mvc "xsi: schemalocation= "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 Http://www.springframework.org/schema/mvc http://w Ww.springframework.org/schema/mvc/spring-mvc-3.0.xsd > <!--scan all classes in a Web package to complete bean creation and automatic dependency injection-&lt  ; Context:component-scan base-package= "Com.welljoint"/> <!--activating annotation-based configuration @RequestMapping, @ExceptionHandler, data binding , @NumberFormat, @DateTimeFormat, @ContRoller, @Valid, @RequestBody, @ResponseBody <mvc:annotation-driven/> <!--view Layer configuration--   
        <bean class= "Org.springframework.web.servlet.view.InternalResourceViewResolver" > <!--configuration jstl expression-- <property name= "Viewclass" value= "Org.springframework.web.servlet.view.JstlView"/> <!--prefix- -<property name= "prefix" value= "/web-inf/view/"/> <!--suffix---<property name = "suffix" value= ". jsp"/> </bean> <!--Configure static resources--<mvc:resources location= "/res/" Mappin   g= "/res/**"/> </beans>
 
 3.7 Configure Web. XML with the following code:   
<?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" xmlns:web= "http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi: schemalocation= "Http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id= "Webapp_
    ID "version=" 3.0 "> <display-name>testSSH2</display-name> <!--requests are given to Dispatcherservlet processing <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframe Work.web.servlet.dispatcherservlet</servlet-class> <init-param> &LT;PARAM-NAME&GT;CONTEXTC Onfiglocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </ 
        init-param> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern&gT </servlet-mapping> <!--Add Chinese garbled filter--<filter> <filter-name>characterencodingfilt Er</filter-name> <filter-class>org.springframework.web.filter.characterencodingfilter</ filter-class> </filter> <filter-mapping> <filter-name>characterencodingfilter</fil

If you follow the above step, you can already run the effect, the effect diagram is as follows:

Any input click Login, the following image:

 
3.8 Write Service layer: Create a new Com.welljoint.service package in Src/main/java; Create a new Loginservice.java interface in this package as a service layer 
Package com.welljoint.service;

Public interface Loginservice {public
    int login (String username,string password);
}
Then create a new Loginserviceimpl.java in the Com.welljoint.service package as a service layer interface implementation
Package com.welljoint.service;

Import Org.springframework.stereotype.Service;

@Service public
class Loginserviceimpl implements loginservice{
