之前也曾提出过类似的问题，我经历了所有这些问题，但未能解决问题。相关问题-Q1，Q2，Q3，Q4，Q5，Q6

我有一个带有Spring Boot的Spring Batch项目，并尝试使用数据库连接池。我正在使用8.5.x版的嵌入式tomcat容器。

如果我使用application.properties来指定数据源和池设置，则一切正常。

但是当我尝试使用JNDI时，出现异常-

Caused by: java.lang.ClassNotFoundException: org.apache.tomcat.dbcp.dbcp2.BasicDataSourceFactory

我tomcat-dbcp-**在Mavenjar中看不到任何jar名称，因此不确定是否需要包含任何新的依赖项或需要设置默认数据源工厂以及如何进行处理。

以下是我设置的JNDI bean，Question。我已经清空了某些值。

@Bean
    public TomcatEmbeddedServletContainerFactory embeddedServletContainerFactory(){
        return new TomcatEmbeddedServletContainerFactory() {

            @Override
            protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(
                    Tomcat tomcat) {
                tomcat.enableNaming();
                return super.getTomcatEmbeddedServletContainer(tomcat);
            }

            @Override
            protected void postProcessContext(Context context) {
                ContextResource resource = new ContextResource();
                resource.setName("jdbc/myDataSource");
                resource.setType(DataSource.class.getName());
                resource.setProperty("driverClassName", "com.ibm.db2.jcc.DB2Driver");
                resource.setProperty("url", "url");
                resource.setProperty("username", "user");
                resource.setProperty("password", "*****");
                context.getNamingResources().addResource(resource);
            }
        };
    }

    @Lazy
    @Bean(destroyMethod="")
    public DataSource jndiDataSource() throws IllegalArgumentException, NamingException {
        JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
        bean.setJndiName("java:comp/env/jdbc/myDataSource");
        bean.setProxyInterface(DataSource.class);
        bean.setLookupOnStartup(false);
        bean.afterPropertiesSet();
        return (DataSource)bean.getObject();
    }
