springboot2.x Embedded Tomcat 配置jndi

对于Embedded Tomcat的话，需要添加ServletWebServerFactory进行配置

• 配置ServletWebServerFactory

@Configuration
public class JNDIConfig {

    @Bean
    public ServletWebServerFactory webServerFactory() {
        TomcatServletWebServerFactory tomcatServletWebServerFactory = new TomcatServletWebServerFactory(){
            @Override
            protected TomcatWebServer getTomcatWebServer(Tomcat tomcat) {
                // 启用默认禁用的JNDI命名
                tomcat.enableNaming();
                return super.getTomcatWebServer(tomcat);
            }
            @Override
            protected void postProcessContext(Context context) {
                ContextResource resource = new ContextResource();
                resource.setName("jdbc/orcl");
                resource.setType(DataSource.class.getName());
                resource.setProperty("driverClassName", "oracle.jdbc.driver.OracleDriver");
                resource.setProperty("url", "jdbc:oracle:thin:@192.168.11.245:1521/Base");
                resource.setProperty("username", "U_JSP");
                resource.setProperty("password","U_JSP");
                context.getNamingResources().addResource(resource);
                super.postProcessContext(context);
            }
        };
        return tomcatServletWebServerFactory;
    }
}

• 配置application.properties

## springdata source jndi
#   spring.datasource.jndi-name=java:comp/env/jdbc/orcl
spring.datasource.jndi-name=jdbc/orcl

• 错误一：

• 解决：
  • 在配置中加入resource.setProperty("factory", "org.apache.tomcat.jdbc.pool.DataSourceFactory");

protected void postProcessContext(Context context) {
                ContextResource resource = new ContextResource();
                resource.setName("jdbc/orcl");
                resource.setType(DataSource.class.getName());
                resource.setProperty("factory", "org.apache.tomcat.jdbc.pool.DataSourceFactory");
                resource.setProperty("driverClassName", "oracle.jdbc.driver.OracleDriver");
                resource.setProperty("url", "jdbc:oracle:thin:@192.168.11.245:1521/Base");
                resource.setProperty("username", "U_JSP");
                resource.setProperty("password","U_JSP");
                context.getNamingResources().addResource(resource);
                super.postProcessContext(context);
            }

• 解决：
  • 添加tomcat-jdbcjar包

        
            org.apache.tomcat
            tomcat-jdbc
            9.0.0.M27
