Method Detail

cacheModulePluginConfig

public static void cacheModulePluginConfig(String realConfigDirectory)

缓存已加载的模块插件配置信息到物理文件

Parameters:

realConfigDirectory - 模块插件配置信息缓存文件夹路径，绝对路径

getNeedUpdateDriverInfos

protected static List<ModulePluginDriverInfo> getNeedUpdateDriverInfos()

getDriverInfos

public static Enumeration<ModulePluginDriverInfo> getDriverInfos()

getDriverInfos

public static Enumeration<ModulePluginDriverInfo> getDriverInfos(Class<? extends ModulePluginDriver> clazz)

获取指定驱动接口的驱动类集合

Parameters:

clazz - 继承ModulePluginDriver接口的子接口

Returns:

getDriverInfo

public static ModulePluginDriverInfo getDriverInfo(String driverClassName)
                                            throws DriverNotExistException

根据模块驱动类名称，获取模块驱动类详细信息

Parameters:

driverClassName - 模块驱动类名称，字符串（包括包路径）

Returns:

如果不存在抛出异常

Throws:

DriverNotExistException

getDrivers

public static <X> Enumeration<X> getDrivers(Class<X> clazz)

getResources

protected static org.springframework.core.io.Resource[] getResources(ModulePluginDriverInfo driverInfo,
                                                                     String pattern)

根据ClassRelativeResourceLoader加载符合pattern的资源

Parameters:

loaderClass - 定位class

pattern - 匹配符

Returns:

可能为null

resolvePath

protected static String resolvePath(Class<? extends ModulePluginDriver> loaderClass,
                                    String path)

根据指定class处理path，如果path为null，则返回null；如果path以"/"Begin，则直接返回path； 如果path不以"/"开始，那么返回loaderClass所在包的路径再加上path路径。

Parameters:

loaderClass - 指定class，根据该clas所在的包来定位path的最终路径

path - 包的相对路径，或者是相对于loaderClass的相对路径

Returns:

可能为null
