What is SpringMVC?

The Spring web MVC framework provides model-view-controller architecture and ready components that can be used to develop flexible and loosely coupled web applications.

The MVC pattern results in separating the different aspects of the application (input logic, business logic, and UI logic), while providing a loose coupling between these elements.

– The Model encapsulates the application data and in general they will consist of POJO.

– The View is responsible for rendering the model data and in general it generates HTML output that the client's browser can interpret.

– The Controller is responsible for processing user requests and building appropriate model and passes it to the view for rendering.

Prepare Tomcat

Download the latest Tomcat Server from http://tomcat.apache.org/

– apache-tomcat-8.0.14-windows-x86.zip (32 bit version)

– apache-tomcat-8.0.14-windows-x64.zip (64 bit version)

Install the latest Tomcat Server

– unzip apache-tomcat-8.0.14-windows-x64.zip to D:\

– check directory name : D:\apache-tomcat-8.0.14



Combining SpringMVC and Hibernate

Adding the SpringMVC as a project dependency

build.gradle :

dependencies {

compile 'org.springframework:spring-webmvc:4.+'

compile( 'org.springframework:spring-core:4.+' ) {exclude group: 'commons-logging', module: 'commons-logging'

}compile 'org.springframework:spring-context:4.+'compile 'org.springframework:spring-orm:4.+'

runtime 'org.slf4j:jcl-over-slf4j:1.+'}



Setup Gradle for Web Application …

Setup gradle-cargo-plugin

build.gradle :

buildscript {repositories {jcenter()

}dependencies {classpath 'com.bmuschko:gradle-cargo-plugin:2.1.1'

}}

ext {cargoVersion = '1.+' // 1.4.10tomcatVersion = '8.0.14'

}

apply plugin: 'war' // providedCompile, providedRuntimeapply plugin: 'com.bmuschko.cargo' // cargoRunLocalapply plugin: 'eclipse-wtp' // eclipse




Setup gradle-cargo-plugin

cargoRunLocal {dependsOn war

}

cargo {containerId = 'tomcat8x'port = 8080

deployable {//file = file("build/libs/${project.name}.war")context = 'springmvc'

}

local {homeDir = file("D:/apache-tomcat-${tomcatVersion}")outputFile = file('build/output.log')

}}
