目前我在控制器和HibernateTemplate之间遇到Autowire配置问题。
我无法追查错误。
下面给出了我的调度程序servlet，java控制器和错误我想做自动连接的Hibernate模板但是它给出了这个错误 需要手动提供hibernate模板的实现

要启用@Autowired，您必须注册'AutowiredAnnotationBeanPostProcessor'，您可以通过两种方式执行此操作：
<context:annotation-config /> 在Spring配置文件中添加Spring上下文。
<beans
//...
xmlns:context="http://www.springframework.org/schema/context"
">
//...
<context:annotation-config />
//...
</beans>
直接在bean配置文件
中包含'AutowiredAnnotationBeanPostProcessor'<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
..>
<bean
class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>
...
</beans>

在您的应用程序上下文中没有类型为HibernateTempate的bean。
添加这些行
<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory"><ref bean="sessionFactory"/></property>
</bean>
在用户使用休眠模板之前，请先查看此answer。

您需要在弹簧配置中启用注释，尝试在弹簧配置中添加以下内容：
private static final ThreadLocal<ObjectMapper> objectMapperThreadLocal = new ThreadLocal<>();
public static ObjectMapper getObjectMapper() {
ObjectMapper objectMapper = objectMapperThreadLocal.get();
if (objectMapper == null) {
objectMapper = new ObjectMapper();
objectMapperThreadLocal.set(objectMapper);
}
return objectMapper;
}
