application.yml 中加入

spring:
      datasource:
        jndi-name: jdbc/xxx

加入config:

import org.apache.catalina.startup.Tomcat;
    import org.apache.tomcat.util.descriptor.web.ContextResource;
    import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
    import org.springframework.boot.web.embedded.tomcat.TomcatWebServer;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.jndi.JndiObjectFactoryBean;
    
    import javax.naming.NamingException;
    import javax.sql.DataSource;
    
    @Configuration
    public class TomcatConfigs {
    
        @Bean
        public TomcatServletWebServerFactory tomcatFactory() {
    
            return new TomcatServletWebServerFactory() {
                @Override
                protected TomcatWebServer getTomcatWebServer(Tomcat tomcat) {
                    tomcat.enableNaming();
                    return super.getTomcatWebServer(tomcat);
                }
    
                @Override
                protected void postProcessContext(Context context) {
                    ContextResource resource = new ContextResource();
                    resource.setType(DataSource.class.getName());
                    resource.setName("jdbc/xxxx");
                    resource.setProperty("factory", "org.apache.commons.dbcp2.BasicDataSourceFactory");
                    resource.setProperty("driverClassName", "oracle.jdbc.driver.OracleDriver");
                    resource.setProperty("url", "jdbc:oracle:thin:@xxx:xxx:xxx");
                    resource.setProperty("username", "xxx");
                    resource.setProperty("password", "xxx");
    
                    context.getNamingResources().addResource(resource);
                }
            };
        }
    
        @Bean
        public DataSource jndiDataSource() throws IllegalArgumentException, NamingException {
            JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
            bean.setJndiName("java:/comp/env/jdbc/xxxx");
            bean.setProxyInterface(DataSource.class);
            bean.setLookupOnStartup(false);
            bean.afterPropertiesSet();
            return (DataSource) bean.getObject();
        }
    }
