Spring (12) Spring Integration MyBatis

First, the first step depends on:

<!--mybatis+spring Integration--
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>1.2.1</version>
</dependency>
<!--Spring Integrated Javaweb Package--
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>4.2.0.RELEASE</version>
</dependency>
<!--mybatis Jar Pack--
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.2.2</version>
</dependency>
<!--jstl Expressions--
<dependency>
<groupId>jstl</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>

<!--Spring Integrated Javaweb Package--
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>4.2.0.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.2.0.RELEASE</version>
</dependency>

2. Create a database: Make a simple add:

You have to create two JSPs.

3. Write Dao,service,entity,servlet

Implementation class

DAO layer

Service

Then there's the servlet.

protected void DoPost (HttpServletRequest request, httpservletresponse response) throws Servletexception, IOException {
Request.setcharacterencoding ("Utf-8");
String name = Request.getparameter ("BookName");
String author = request.getparameter ("Bookauthor");
String Bookprice = Request.getparameter ("Bookprice");
Integer Price = Integer.parseint (Bookprice);

Book book = new book ();
Book.setbookname (name);
Book.setbookauthor (author);
Book.setbookprice (price);

ApplicationContext context = new Classpathxmlapplicationcontext ("Applicationcontext18ssm.xml");
ApplicationContext context = Webapplicationcontextutils.getrequiredwebapplicationcontext (This.getServletContext () );
Ibookservice service= (Ibookservice) Context.getbean ("Bookservice");
try {
int count= service.addbook (book);
if (count>0) {
Request.getrequestdispatcher ("/index.jsp"). Forward (Request,response);
}else {
Response.sendredirect ("/addbook.jsp");
}
} catch (Exception e) {
E.printstacktrace ();
}


}

protected void doget (HttpServletRequest request, httpservletresponse response) throws Servletexception, IOException {
DoPost (Request,response);
}
