在使用mybatis 3.0的annotation之后，会产生大量mapper接口文件。

		addExcludeFilter(new TypeFilter() {

	public MybatisMapperScanner() {
		super(false);

	 * 
	 * @param packageName
	 *            包名，如"com.iteye.strongzhu"
	 * 
	 * @return 所有的mapper清单

		final Set components = findCandidateComponents(packageName);

		final Set> mybatisMapperList = new HashSet>();
		for (final BeanDefinition component : components) {
