Maven + spring + SPRINGMVC + Spring JPA <1>

Old, a frame with a day and a half, stumbled, calculate the basic pass, record the process and the problems used during.

have been too lazy to use maven, afraid of trouble, this time use is because Spring official website revision, must use Maven way to download, preliminary use, quite good, can rely on the package to download down, but the trouble is, in Eclipse build project time, not so smooth, For example, Web.xml also need to be created manually. Configure the project to use the package is also, you need to find Maven whether to support the package, but also have to write a version of, and so on, check the package URL is:

http://central.maven.org/maven2/oracle/toplink/essentials/

I'm using Myeclipse10, and I don't have to talk to you. Configure the folder mapping relationship and so on, directly create the MAVEN project project:

The above two steps can be, and then create a web.xml under the Src/main/webapp/web-inf, and then casually the entire JSP, the project published to Tomcat, directly can be used.

The next is the whole jar package process, used a lot of time to find the project root directory of the Pom.xml file, add the package, after a few articles may increase or decrease, will be explained in the post

After the save, MAVEN will go to the Web site to download the relevant jar bag and dependencies, this is very cool, but find version number, quite laborious, familiar with after a lot better.

Configure Web.xml

<?xml version= "1.0" encoding= "UTF-8"?> <web-app version= "2.5" xmlns= "Http://java.sun.com/xml/ns/javaee" Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xsi:schemalocation= "Http://java.sun.com/xml/ns/javaee http ://java.sun.com/xml/ns/javaee/web-app_2_5.xsd "> <servlet> <servlet-name>springmvc</

Create a Applicationcontext.xml file under Src/main/java/config file

<?xml version= "1.0" encoding= "UTF-8"?> <beans xmlns= "Http://www.springframework.org/schema/beans" xmlns:x Si= "Http://www.w3.org/2001/XMLSchema-instance" xmlns:context= "Http://www.springframework.org/schema/context" x mlns:aop= "HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP" xmlns:tx= "Http://www.springframework.org/schema/tx" xmlns :p = "http://www.springframework.org/schema/p" xmlns:cache= "Http://www.springframework.org/schema/cache" xmlns:j Pa= "HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/DATA/JPA" xsi:schemalocation= "http://www.springframework.org/schema/ Beans Http://www.springframework.org/schema/beans/spring-beans-3.1.xsd Http://www.springframewor K.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http:/

Then create a Springmvc-servlet.xml

<?xml version= "1.0" encoding= "UTF-8"?> <beans xmlns=
"Http://www.springframework.org/schema/beans"
    xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance"

    http://www.springframework.org/schema/context/ Spring-context-3.2.xsd ">
   

    <!--enable spring MVC annotations-->    
	<context:annotation-config/>  
    <!--setting the jar package where the annotations are used-->    
	< Context:component-scan base-package= "Org.mice"/>

<bean class= "Org.springframework.web.servlet.view.UrlBasedViewResolver" ><!--Specify policy resolution--><property Name= "Viewclass" value= "Org.springframework.web.servlet.view.JstlView"/><!--Specify view handling--><property name= "prefix" value= "/jsp/"/><!--prefix--><property name= "suffix" value= ". jsp"/><!--suffix--> </bean > </beans>

Finally, in src/main/java/ Meta-inf under the creation of persistence.xml files, using the hibernate of the JPA implementation, learning, can pass on the line, the whole, database direct use of Oracle, because MAVEN does not have the Oracle driver, I did not use the online manual to add to the local Maven library way, straight is then configured in the project through Eclipse.
