    <p>I am using the @Autowired annotation with spring-mvc and spring-security, it works, but the webapp start very slow, about 1 munute every time, because the spring-mvc and spring-security scan twice all autowired classes and the total count of classes about 500. Are there any suggestions to speed up the scan time? or the static xml configuration is better?</p> <p>in web.xml</p> <pre><code>&lt;context-param&gt; &lt;param-name&gt;contextConfigLocation&lt;/param-name&gt; &lt;param-value&gt; /WEB-INF/rest-servlet.xml &lt;/param-value&gt; &lt;/context-param&gt; &lt;filter&gt; &lt;filter-name&gt;springSecurityFilterChain&lt;/filter-name&gt; &lt;filter-class&gt;org.springframework.web.filter.DelegatingFilterProxy&lt;/filter-class&gt; &lt;/filter&gt; &lt;filter-mapping&gt; &lt;filter-name&gt;springSecurityFilterChain&lt;/filter-name&gt; &lt;url-pattern&gt;/*&lt;/url-pattern&gt; &lt;/filter-mapping&gt; &lt;servlet&gt; &lt;servlet-name&gt;rest&lt;/servlet-name&gt; &lt;servlet-class&gt;org.springframework.web.servlet.DispatcherServlet&lt;/servlet-class&gt; &lt;load-on-startup&gt;2&lt;/load-on-startup&gt; &lt;/servlet&gt; &lt;servlet-mapping&gt; &lt;servlet-name&gt;rest&lt;/servlet-name&gt; &lt;url-pattern&gt;/&lt;/url-pattern&gt; &lt;/servlet-mapping&gt; .... </code></pre> <p>in rest-sevlet.xml</p> <pre><code> &lt;context:component-scan base-package="com.mycomp" /&gt; &lt;mvc:annotation-driven /&gt; &lt;mvc:interceptors&gt; .... &lt;/mvc:interceptors&gt; &lt;import resource="classes/config/applicationContext-security-base.xml"/&gt; &lt;import resource="classes/config/applicationContext-security.xml"/&gt; &lt;import resource="classes/config/spring-aop.xml"/&gt; &lt;!-- i18n --&gt; &lt;import resource="classes/config/spring-locale.xml"/&gt; </code></pre>

    1. COWhy would the classes be scanned twice?! Spring Security only scans defined beans (i.e. `@Components` in the context). component-scan scans the classpath for beans. If that is wrongly configured you can have duplicate beans. And next to that why is the startup-time a problem? Anyway post some configuration and your web.xml.

    2. COUse a profiler to see where the time is going. Spring is usually quick to start up, but some of your beans might take time (eg Hibernate?)

    3. COScan twice it coused by spring-mvc sevlet (rest-servlet) and spring-security filter, I think. Both they are need a separated spring-context.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
