SpringMVCboot

build.gradle:

apply plugin: 'groovy'
apply plugin: 'war'
apply plugin: 'jetty'

sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    mavenLocal()
    mavenCentral()
}

def springVersion = '4.1.7.RELEASE'
def groovyVersion = '2.4.5'
def aspectjVersion = '1.8.7'
def currentEnvironment = project.hasProperty("environment")?environment:"development"

dependencies {

  compile "org.springframework:spring-webmvc:${springVersion}"
  compile "org.codehaus.groovy:groovy:${groovyVersion}"
  compile 'log4j:log4j:1.2.17'

}

jettyRun{
  contextPath = "jmailer"
  httpPort = 8080
}

jettyRunWar{
  contextPath = "jmailer"
  httpPort = 8080
}

println "Setting environment to: ${currentEnvironment}"

task settingLog4jProperties(type:Copy){
  from "${System.getProperty('user.home')}/.jmailer/log4j-${currentEnvironment}.properties"
  into "src/main/resources/"
  rename { String fileName -> fileName.replace("-${currentEnvironment}", '') }
}

processResources.dependsOn "settingLog4jProperties"

Spring Boot控制器

@Controller
class EmailerController {

  @Autowired
  EmailerService emailerService

  Log log = LogFactory.getLog(this.class)

  @RequestMapping(value = '/', method = GET)
  String index(Map<String, Object> model) {
    log.debug 'Calling index'
    model.put('title', emailerService.getTitle('World!'))
    model.put('msg', emailerService.getDescription())

    return 'index'
  }
}

 服務：

@Service
class EmailerService {

  Log log = LogFactory.getLog(this.class)

  String getTitle(String name) {
    log.debug "GETTING title with name : ${name}"
    "Hello ${name}"
  }

  String getDescription() {
    log.debug "GETTING description"
    "Jmailer is a service for delivering emails"
  }

}

檢視：

JSP + JSTL + bootstrap。一個簡單的JSP頁面，用於顯示模型，幷包含靜態資源，如css和js。

Spring XML配置

根目錄下建立一個名為.jmailer的資料夾並新增此log4j檔案

檔案：log4j-development.properties

#
# The logging properties used for eclipse testing, We want to see INFO output on the console.
#
log4j.rootLogger=out

log4j.logger.com.jos.dem=DEBUG,out
log4j.logger.org.springframework=INFO,out
log4j.logger.org.springframework.transaction=DEBUG

log4j.logger.org.displaytag=ERROR,out
log4j.logger.net.sf=ERROR,out

#Ensure the logs don't add to each other

log4j.additivity.org.hibernate=false

log4j.appender.out.layout=org.apache.log4j.PatternLayout
log4j.appender.out.layout.ConversionPattern=%d %5p [%t] (%F:%L) - %m%n

主目錄並鍵入：

gradle jettyRun

進入瀏覽器：http：// localhost：8080 / jmailer /

原始碼下載： 

git clone https://github.com/josdem/jmailer-bootstrap.git
git fetch
git checkout setup
