 Class<T> clazz)
                           throws org.springframework.beans.BeansException

获取bean实例

获取bean实例

抛出:

org.springframework.beans.BeansException

getBeansOfType

public static <T> Map<String,T> getBeansOfType(Class<T> clazz)

获取此类型所有的bean

参数:

clazz -

返回:

抛出:

org.springframework.beans.BeansException

getSingleBeanByType

public static <T> T getSingleBeanByType(Class<T> clazz)
                                 throws Exception

根据class 类型获取bean

参数:

clazz -

返回:

抛出:

org.springframework.beans.BeansException - 当有继承或者接口时(多个实现类)getBean(clazz)会报错 所以通过class name比较来获取唯一那个bean
