项目的异常 Spring Hibernate Jndi Tomcat
Project's exception Spring Hibernate Jndi Tomcat
我创建了我的项目，现在我正在尝试 运行 它，但我发现了异常，这让我明白了 jdbc 中的问题，也许是在 jndi 连接中。

更新：
我用 'no suitable driver' 解决了这个问题。我是这样修复的：
<build>
<finalName>ApplicationAnnotations</finalName>
<plugins>
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<configuration>
<url>http://localhost:8080/manager/text</url>

<artifactId>mysql-connector-java</artifactId>
<version>5.1.34</version>
<scope>compile</scope>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>
相反 "no suitable driver" 我已经有 NullPointerException 错误
JNDI 中的问题，因为当我替换
@Bean(name = "dataSource")
public DataSource getDataSource() {
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName("com.mysql.jdbc.Driver");
dataSource.setUrl("jdbc:mysql://localhost:3306/cms");
dataSource.setUsername("root");
dataSource.setPassword("admin");
return dataSource;
}
改为
// @Bean(name="dataSource")
// public DataSource getDataSource(){
// JndiDataSourceLookup dsLookup = new JndiDataSourceLookup();
// DataSource dataSource = dsLookup.getDataSource("jdbc/cms");
// return dataSource;
// }
项目开始正常工作。
java.sql.SQLException: No suitable driver

org.apache.tomcat.dbcp.dbcp.BasicDataSource.createConnectionFactory(BasicDataSource.java:1437)
如果数据源由您的服务器配置定义和管理，JDBC 驱动程序需要位于服务器的 class 路径上。
将您的 mysql-connector-java-5.1.34.jar 放入 ${CATALINA_HOME}/lib（有点脏的解决方案，因为您将自定义 JAR 与适当的服务器 JAR 混在一起）。
如果您不想要更漂亮的解决方案，请将 JAR 放在 ${CATALINA_HOME}/lib/ext 中（需要篡改 catalina.properties 中常见的 class 加载程序位置）。
从 JNDI 获取数据源时，您不需要将 JDBC 驱动程序作为依赖项包含在您的 Web 应用程序中（即您可以从 pom.xml 中删除它）。
我创建了我的项目，现在我正在尝试 运行 它，但我发现了异常，这让我明白了 jdbc 中的问题，也许是在 jndi 连接中。

更新：
我用 'no suitable driver' 解决了这个问题。我是这样修复的：
<build>
<finalName>ApplicationAnnotations</finalName>
<plugins>
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<configuration>
<url>http://localhost:8080/manager/text</url>
<server>tomcatserver</server>
</configuration>
<dependencies>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.34</version>
<scope>compile</scope>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>
相反 "no suitable driver" 我已经有 NullPointerException 错误
JNDI 中的问题，因为当我替换
@Bean(name = "dataSource")
public DataSource getDataSource() {
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName("com.mysql.jdbc.Driver");
dataSource.setUrl("jdbc:mysql://localhost:3306/cms");
dataSource.setUsername("root");
dataSource.setPassword("admin");
return dataSource;
}
改为
// @Bean(name="dataSource")
// public DataSource getDataSource(){
// JndiDataSourceLookup dsLookup = new JndiDataSourceLookup();
// DataSource dataSource = dsLookup.getDataSource("jdbc/cms");
// return dataSource;
// }
项目开始正常工作。

如果数据源由您的服务器配置定义和管理，JDBC 驱动程序需要位于服务器的 class 路径上。
将您的 mysql-connector-java-5.1.34.jar 放入 ${CATALINA_HOME}/lib（有点脏的解决方案，因为您将自定义 JAR 与适当的服务器 JAR 混在一起）。
如果您不想要更漂亮的解决方案，请将 JAR 放在 ${CATALINA_HOME}/lib/ext 中（需要篡改 catalina.properties 中常见的 class 加载程序位置）。
从 JNDI 获取数据源时，您不需要将 JDBC 驱动程序作为依赖项包含在您的 Web 应用程序中（即您可以从 pom.xml 中删除它）。
