Question

我正在使用gradle作为构建工具和Mysql作为jndi数据源创建一个spring mvc应用程序。我可以通过构建war并手动部署它来运行它。但是，当我尝试使用gretty运行它时，我得到以下异常

javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial

这是我的build.gradle文件： -

apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'eclipse-wtp'
//apply plugin: 'jetty' //too old, Jetty6, use gretty
apply plugin: 'org.akhikhl.gretty'
apply plugin: 'idea'
apply plugin: 'jacoco' //code coverage

def springVersion = "4.2.4.RELEASE"
def jdkVersion = 1.8
def junitVersion = "4.12"
def logbackVersion = "1.1.3"
def jclOverSlf4jVersion = "1.7.14"
def jstlVersion = "1.2"
def hamcrestVersion = "1.3"
def servletApiVersion = "3.1"
def mysqlVersion = "5.1.31"

sourceCompatibility = jdkVersion
targetCompatibility = jdkVersion

repositories {
    mavenLocal()
    mavenCentral()
}

task wrapper(type: Wrapper) {
    gradleVersion = '2.10'
}

configurations.all {
    exclude group: "commons-logging", module: "commons-logging"
}

dependencies {

    compile 'org.slf4j:jcl-over-slf4j:' + jclOverSlf4jVersion
    compile 'ch.qos.logback:logback-classic:' + logbackVersion
    compile 'org.springframework:spring-webmvc:' +springVersion
    compile 'org.springframework:spring-context:' + springVersion
    compile 'org.springframework:spring-orm:' + springVersion
    compile 'javax.servlet:jstl:' + jstlVersion
    compile 'org.springframework:spring-test:' + springVersion
    compile 'mysql:mysql-connector-java:' + mysqlVersion
    //exclude the build in hamcrest
    testCompile('junit:junit:' + junitVersion) {
        exclude group: 'org.hamcrest'
    }
    testCompile 'org.hamcrest:hamcrest-library:' + hamcrestVersion
    //include in compile only, exclude in the war
    providedCompile 'javax.servlet:javax.servlet-api:' + servletApiVersion

}

//Gretty
buildscript {
  repositories {
    jcenter()
  }

  dependencies {
    classpath 'org.akhikhl.gretty:gretty:1.1.5'
  }
}

gretty {
  port = 9090
  contextPath = 'loanSharks'
  servletContainer = 'tomcat8'
}



//For Eclipse IDE only
eclipse {

  wtp {
    component {

      //define context path, default to project folder name
      contextPath = 'loanSharks'

    }

  }
}

jacoco {
    toolVersion = "0.7.5+"
    reportsDir = file("$buildDir/reports/jacoco")
}

jacocoTestReport {
    reports {
        xml.enabled = true
        html.enabled = true
    }
}

这是我在web.xml中的jndi条目： -

<resource-ref>
        <res-ref-name>jdbc/devcore</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <res-auth>Container</res-auth>
    </resource-ref>

这是我在spring-config文件中的条目： -

<bean id="dataSource"
    class="org.springframework.jndi.JndiObjectFactoryBean">
        <property name="jndiName" value="java:comp/env/jdbc/devcore" /> 
        <property name="lookupOnStartup" value="true"/>
        <property name="proxyInterface" value="javax.sql.DataSource"/>
    </bean>

我还在META-INF / context.xml文件和META-INF / jetty-env.xml文件中有我的数据库条目，正如在其他一些相关帖子中所建议的那样。所以任何人都可以解释为什么我无法使用gretty来运行我的应用程序。

您需要在gretty配置中激活命名：

gretty {
  enableNaming = true
}

带有mysql DataSource和gretty的javax.naming.NoInitialContextException
