从Spring Boot 3.0.x到3.1.x的迁移中断了自动布线

    我正在从SpringBoot 3.0.11迁移到SpringBoot 3.1.4 到目前为止,我收到了一个关于servlet注册的警告,3.1中的内容会导致错误。 为了保持相同的行为,我更改了代码如下。 但现在自动布线坏了。

    任何小费,我做错了什么

    这是我在SpringBoot 3.0.11中的代码 

    @EnableConfigurationProperties({ DataSourceMonitoringProperties.class})
public class DataSourceServletConfiguration {
    
    public static final String DATASOURCE_MONITORING_PATH = "/datasource";

    @Bean(name = Const.DATASOURCE_SERVLET_BEAN_NAME)
    @ConditionalOnMissingBean(name = Const.DATASOURCE_SERVLET_BEAN_NAME)
    public Servlet monitoringDatasourceServlet(ServletContext servletContext, DataSourceMonitoringProperties dataSourceMonitoringProperties) {
        RequestDispatcher namedDispatcher = servletContext.getNamedDispatcher(Const.DATASOURCE_SERVLET_BEAN_NAME);
        if (namedDispatcher != null) {
            return new DataSourceMonitoringServlet();
        }

        DataSourceMonitoringServlet monitoringDatasourceServlet = new DataSourceMonitoringServlet();
        monitoringDatasourceServlet.setJavamelody(null != servletContext.getFilterRegistration("javamelody"));
        Dynamic monitoringDataSourceServletDynamic = servletContext.addServlet(Const.DATASOURCE_SERVLET_BEAN_NAME, monitoringDatasourceServlet);
        monitoringDataSourceServletDynamic.setLoadOnStartup(1);
        monitoringDataSourceServletDynamic.setAsyncSupported(true);
        monitoringDataSourceServletDynamic.addMapping(DATASOURCE_MONITORING_PATH);


        return monitoringDatasourceServlet;
    }

    我不得不将其更改为以下内容,以使其与Springboot 3.0.11兼容

    monitoringDatasourceServlet注册。setIgnoreRegistrationFailure(true); 

        @Bean(name = Const.DATASOURCE_SERVLET_BEAN_NAME)
    @ConditionalOnMissingBean(name = Const.DATASOURCE_SERVLET_BEAN_NAME)
    public ServletRegistrationBean<DataSourceMonitoringServlet> monitoringDatasourceServlet(ServletContext servletContext, DataSourceMonitoringProperties dataSourceMonitoringProperties) throws ServletException {
        RequestDispatcher namedDispatcher = servletContext.getNamedDispatcher(Const.DATASOURCE_SERVLET_BEAN_NAME);
        if (namedDispatcher != null) {
            ServletRegistrationBean<DataSourceMonitoringServlet> servletRegistrationBean = new ServletRegistrationBean<>(new DataSourceMonitoringServlet());
            servletRegistrationBean.onStartup(servletContext);
            return servletRegistrationBean;
        }

        DataSourceMonitoringServlet monitoringDatasourceServlet = new DataSourceMonitoringServlet();
        monitoringDatasourceServlet.setJavamelody(null != servletContext.getFilterRegistration("javamelody"));
        Dynamic monitoringDataSourceServletDynamic = servletContext.addServlet(Const.DATASOURCE_SERVLET_BEAN_NAME, monitoringDatasourceServlet);
        monitoringDataSourceServletDynamic.setLoadOnStartup(1);
        monitoringDataSourceServletDynamic.setAsyncSupported(true);
        monitoringDataSourceServletDynamic.addMapping(DATASOURCE_MONITORING_PATH);
        
        ServletRegistrationBean<DataSourceMonitoringServlet> monitoringDatasourceServletRegistration = new ServletRegistrationBean<>(monitoringDatasourceServlet, DATASOURCE_MONITORING_PATH);
        monitoringDatasourceServletRegistration.onStartup(servletContext);
        ** monitoringDatasourceServletRegistration.setIgnoreRegistrationFailure(true); **
        monitoringDatasourceServletRegistration.setLoadOnStartup(1);
        monitoringDatasourceServletRegistration.setAsyncSupported(true);


        return monitoringDatasourceServletRegistration;
    }

    在测试执行期间,Servlet被调用,并在

    data.setCollectedDatasourceTraces(datasourceMetricsCollector.collecteDatasourceMetrics()); 

    public class DataSourceMonitoringServlet extends GenericServlet {

    @Autowired
    private DatasourceMetricsCollector datasourceMetricsCollector;
    private boolean javamelody;

    public HtmlReportData datasourceReport() {
        // curl -i -H "Accept: application/json" http://localhost:8080
        HtmlReportData data = new HtmlReportData();
        data.setCollectedDatasourceTraces(datasourceMetricsCollector.collectDatasourceMetrics());
        data.setFindLockRows(datasourceMetricsCollector.collectRecordLockInfo());
        return data;
    }

    这是我在测试执行中得到的Stacktrace

    您的代码既奇怪又复杂。您应该有两个简单的bean:一个用于servlet,一个用于注册。你添加的所有其他内容都很混乱。 

    public static final String DATASOURCE_MONITORING_PATH = "/datasource";

@Bean(name = Const.DATASOURCE_SERVLET_BEAN_NAME)
@ConditionalOnMissingBean(name = Const.DATASOURCE_SERVLET_BEAN_NAME)
public DataSourceMonitoringServlet monitoringDatasourceServlet(DataSourceMonitoringProperties dataSourceMonitoringProperties, ServletContext ctx) {
    var monitoringDatasourceServlet = new DataSourceMonitoringServlet();
    monitoringDatasourceServlet.setJavamelody(null != ctx.getFilterRegistration("javamelody"));
    return monitoringDatasourceServlet;
}

@Bean
public ServletRegistrationBean< DataSourceMonitoringServlet > servletRegistation(DataSourceMonitoringServlet servlet) {
 var registration = new ServletRegistrationBean(servlet, DATASOURCE_MONITORING_PATH);
 registration.setLoadOnStartup(1);
 return registration;

}

    Spring Boot将在上下文中处理此bean和servlet的注册。你不应该自己做这件事,尤其是在 @Bean 方法
