- * <pre class="code"> driver=com.mysql.jdbc.Driver
+ * <pre class="code">driver=com.mysql.jdbc.Driver

  * Annotated bean definitions may take advantage of property replacement using
  * the {@link org.springframework.beans.factory.annotation.Value @Value} annotation:
  *
- *<pre class="code">@Value("${person.age}")</pre>
+ * <pre class="code">@Value("${person.age}")</pre>
  *
  * Implementations check simple property values, lists, maps, props, and bean names
  * in bean references. Furthermore, placeholder values can also cross-reference
  * other placeholders, like:
  *
- *<pre class="code">rootPath=myrootdir
- *subPath=${rootPath}/subdir</pre>
+ * <pre class="code">rootPath=myrootdir
+ * subPath=${rootPath}/subdir</pre>
  *
  * In contrast to {@link PropertyOverrideConfigurer}, subclasses of this type allow
  * filling in of explicit placeholders in bean definitions.
