Dynamic web project下SSM整合

项目结构示意图：

---

首先配置web.xml文件：

<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"
    id="WebApp_ID" version="2.5">

        <welcome-file>index.htmlwelcome-file>
        <welcome-file>index.htmwelcome-file>
        <welcome-file>index.jspwelcome-file>
        <welcome-file>default.htmlwelcome-file>
        <welcome-file>default.htmwelcome-file>
        <welcome-file>default.jspwelcome-file>
    welcome-file-list>

    
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
    listener>
    


    
    
    <context-param>
        <param-name>contextConfigLocationparam-name>
        <param-value>classpath:spring-*.xmlparam-value>
    context-param>
    

    
    <filter>
        <filter-name>CharacterEncodingFilterfilter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>
        <init-param>
            <param-name>encodingparam-name>
            <param-value>UTF-8param-value>
        init-param>
        <init-param>
            <param-name>forceEncodingparam-name>
            <param-value>trueparam-value>

    <filter-mapping>
        <filter-name>CharacterEncodingFilterfilter-name>

    <servlet-mapping>
        <servlet-name>springmvcservlet-name>
        <url-pattern>*.dourl-pattern>
    servlet-mapping>
    

web-app>

另外，springmvc-servlet.xml文件的配置可以写，也可以不写，其配置如下：

---

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">

    


    
    <context:component-scan base-package="com.wg" use-default-filters="false">
        
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    context:component-scan>

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

    
    
    <mvc:default-servlet-handler/>
    
    <mvc:annotation-driven/>

beans>

---

dbconfig.properties文件配置数据库基本信息：

---

#数据库基本信息配置
jdbc.jdbcUrl=jdbc:mysql://127.0.0.1:3306/ssm?characterEncoding=utf8&useUnicode=true
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.user=root
jdbc.password=123456

---

springMVC的配置如下：

spring-mvc.xml:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/aop 
    http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/tx 
        http://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context.xsd">

    
    <context:component-scan base-package="com.wg.controller">context:component-scan>

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

    
    
    <mvc:default-servlet-handler/>
    
    <mvc:annotation-driven/>

spring的配置如下：

spring配置事务管理，spring-tx.xml：

项目所需的jar包如下：

---

现在开始测试项目搭建是否成功，写一个增加数据的实例：

新建数据库ssm和数据库表student，结构如下：

---

新建如下图所示的包和类：

---

StudentController.java:

@Controller
public class StudentController {
    @Autowired
    public StudentService studentService;

    @RequestMapping("/test/register.do")
    public String register(Student student) {
        System.out.println("public String register(Student student)");
        studentService.studentRegister(student);
        return "success";

    }

}

---

StudentMapper.java

public interface StudentMapper {

    void studentRegister(Student student);

}

---

StudentMapper.xml

<mapper namespace="com.wg.mapper.StudentMapper">

  <insert id="studentRegister" parameterType="com.wg.pojo.Student">
    insert into student(name,age) values(#{name}, #{age})
  insert>

mapper>

---

Student.java

package com.wg.pojo;
/**
* @desc    自定义一个实体类
* @title   Student
* @author  75399
* @version 1.0
*/
public class Student {
    private Integer id;
    private String name;
    private int age;
    public Student(Integer id, String name, int age) {
        super();
        this.id = id;
        this.name = name;
        this.age = age;
    }
    public Student() {
        super();
        // TODO Auto-generated constructor stub
    }
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    @Override
    public String toString() {
        return "Student [id=" + id + ", name=" + name + ", age=" + age + "]";
    }



}

---

StudentService.java

public interface StudentService {

    void studentRegister(Student student);

}

---

StudentServiceImpl.java

@Service
public class StudentServiceImpl implements StudentService {

    @Autowired
    public StudentMapper studentMapper;

    @Override
    public void studentRegister(Student student) {
        // TODO Auto-generated method stub
        studentMapper.studentRegister(student);
    }

}

---

index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title heretitle>
head>
<body>
<form action="${pageContext.request.contextPath}/test/register.do" method="post">
姓名：<input type="text" name="name"><br>
年龄：<input type="text" name="age"><br>
<input type="submit" value="注册">
form>
body>
html>

---

新建views文件夹，新建success.jsp文件格式如下：

---

success.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title heretitle>
head>
<body>
success page!!!
body>
html>

---

现在可以运行项目，项目运行环境jdk1.8，tomcat8.0。

运行效果展示：

姓名是字符串，年龄输入整数，点击注册即可。

查看数据库表：
