[SPRING] HTTP 500 - ''연결 URL에 대해 ''클래스의 JDBC 드라이버를 만들 수 없습니다.

SPRING

HTTP 500 - ''연결 URL에 대해 ''클래스의 JDBC 드라이버를 만들 수 없습니다.

나는 포럼을 읽는 3 일 동안 그 문제를 해결하려고 노력해왔다. 그리고 나는 도움을 청하기로 결정했다. 당신의 도움이 매우 높이 평가 될 것이라고 말할 수는 없지만 :-)

Eclipse에서 Tomcat context.xml 인스턴스의 mysql 연결을위한 jndi 리소스를 만들었습니다. 이클립스에서 서버를 시작할 때 내 웹 응용 프로그램이 제대로 작동합니다. 그 목표와 함께 실행 '구성'에서 일식에서 웹 애플 리케이션을 시작할 때 그것은 잘 작동하지 않습니다 : 깨끗한 바람둥이 : 실행합니다. 내 목표는 구축, 배포, 서버를 maven에서 Eclipse로 시작하도록 위임하는 것입니다.

Tomcat_Home / lib에 mysql-connector-java-5.1.27.jar을 넣었다.

jndi의 목표 중 하나는 데이터 소스 정보를 앱 밖으로 가져 오는 것입니다 (META-INF ....이 아님) app에 데이터 소스 구성을 넣고 싶지 않습니다.

읽어 주셔서 감사 드리며 해결책을 찾기 위해 보내십시오.

해결법

  1. ==============================

    1.귀하의 tomcat 설치가 context.xml을 사용하지 않는 것 같습니다. 신선한 바람둥이를 만들고, context.xml과 libs를 설정하고, Eclipse (Eclipse 제외)에서 직접 Tomcat을 실행하십시오.

    귀하의 tomcat 설치가 context.xml을 사용하지 않는 것 같습니다. 신선한 바람둥이를 만들고, context.xml과 libs를 설정하고, Eclipse (Eclipse 제외)에서 직접 Tomcat을 실행하십시오.

    질문이 업데이트되었습니다. 아래 답변은 더 이상 사용되지 않습니다. /

    중요한 부분은 다음과 같습니다.

    Cannot create JDBC driver of class '' for connect URL 'null'

    드라이버 클래스가 null이며 연결 URL이 null입니다.

    응용 프로그램 구성에는 서버의 구성된 자원 jdbc / TestDB가 필요합니다.

    <resource-ref>
    <description>DB Connection</description>
    <res-ref-name>jdbc/TestDB</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
</resource-ref>

    과

      <jee:jndi-lookup id="dataSource"
    jndi-name="jdbc/TestDB"
    expected-type="javax.sql.DataSource"
    resource-ref="true"/>

    그러나 Tomcat 구성 Servers / tomcat-config / context.xml이 잘못되었습니다. 스프링 애플리케이션 구성과 같습니다.

    <web-app id="WebApp_ID" version="2.4"
    xmlns="http://java.sun.com/xml/ns/j2ee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
                        http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

 ...

    표준 Tomcat context.xml은 다음과 같습니다.

    <?xml version='1.0' encoding='utf-8'?>
<Context>
<Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource" 
    username="user" password="pass"

    src / main / webapp 아래에 META-INF 폴더를 WEB-INF 형제로 만듭니다. Tomcat-config / context.xml 파일을 META-INF 폴더로 이동하십시오. pom.xml에이 파일이 WAR 파일의 일부가 될 수 없다는 것을 알 수 있습니다.

    META-INF / context.xml

    <?xml version="1.0" encoding="UTF-8"?>
<Context>

    <!-- Default set of monitored resources -->
    <WatchedResource>WEB-INF/web.xml</WatchedResource>

 <Resource  name="jdbc/TestDB" 
            username="xxxx" 
            password="xxxxxxxxxx" 
            driverClassName="com.mysql.jdbc.Driver"
            url="jdbc:mysql://localhost:3306/TestDB"
            auth="Container" 
            type="javax.sql.DataSource"
            maxActive="100" 
            maxIdle="30" 
            maxWait="10000"
            initialSize="1"/>
</Context>

    pom.xml 적용

    <plugin>
            <groupId>org.apache.tomcat.maven</groupId>
            <artifactId>tomcat7-maven-plugin</artifactId>
            <version>2.2</version>
            <configuration>
                <url>http://127.0.0.1:8080/manager/text</url>
                <server>TomcatServer</server> <!-- user + password defined in the Maven/conf/settings.xml-->
                <path>/${project.build.finalName}</path>
                <port>8080</port>
                <charset>UTF-8</charset>
                <finalName>${project.build.finalName}</finalName>
                <contextFile>${project.basedir}/src/main/webapp/META-INF/context.xml</contextFile> <!--The path of the Tomcat context XML file. This is not used for war deployment mode.-->
            </configuration>
            <dependencies>
                <dependency>
                    <groupId>mysql</groupId>
                    <artifactId>mysql-connector-java</artifactId> <!-- driver mysql -->
                    <version>5.1.27</version>
                </dependency>
            </dependencies>
        </plugin>

    MAVEN_HOME / conf / settings.xml id는 pom.xml에서 참조됩니다. 사용자 이름과 암호는 tomcat-users.xml에 선언되어 있습니다.

    <server>
    <id>TomcatServer</id>
    <username>xxxxx</username>
    <password>xxxxxxxxx</password>
</server>

    Eclipse / Run - 실행 설정 ...

    다음 번에 ToolBar의 Run As ... 단추 옆에있는 화살표를 클릭하고 실행할 구성을 선택할 수 있습니다. 정지 및 다시 시작 버튼은 매우 유용합니다.
