org.springframework.beans.factory.beancreationexception: error creating bean name 'productscontroller': injection of autowired dependencies failed; nested exception org.springframework.beans.factory.beancreationexception: not autowire field: private com.davis.ty.service.productsservice com.davis.ty.controller.productscontroller.productsservice; nested exception org.springframework.beans.factory.nosuchbeandefinitionexception: no qualifying bean of type [com.davis.ty.service.productsservice] found dependency: expected @ least 1 bean qualifies autowire candidate dependency. dependency annotations: {@org.springframework.beans.factory.annotation.autowired(required=true)} org.springframework.beans.factory.annotation.autowiredannotationbeanpostprocessor.postprocesspropertyvalues(autowiredannotationbeanpostprocessor.java:292)
my servlet.xml is:

package com.davis.ty.controller; import java.util.map; import org.springframework.beans.factory.annotation.autowired; import org.springframework.stereotype.controller; import org.springframework.validation.bindingresult; import org.springframework.web.bind.annotation.modelattribute; import org.springframework.web.bind.annotation.pathvariable; import org.springframework.web.bind.annotation.requestmapping; import org.springframework.web.bind.annotation.requestmethod; import com.davis.ty.domain.products; import com.davis.ty.service.productsservice; @controller public class productscontroller { @autowired private productsservice productsservice; @requestmapping(value = "/index", method = requestmethod.get) public string listproducts (map<string, object> map) { system.out.println("index"); map.put("products", new products()); map.put("productslist", productsservice.listproducts()); return "index"; } @requestmapping(value = "/add", method = requestmethod.post) public string addproducts(@modelattribute("products") products products, bindingresult result) { productsservice.addproducts(products); return "redirect:/index"; } @requestmapping("/delete/{id}") public string deleteproducts(@pathvariable("id") integer id) { productsservice.removeproducts(id); return "redirect:/index"; } } my service program is:
package com.davis.ty.service; import java.util.list; import org.springframework.beans.factory.annotation.autowired; import org.springframework.stereotype.service; import org.springframework.transaction.annotation.transactional; import com.davis.ty.dao.productsdao; import com.davis.ty.domain.products; @service public class productsserviceimpl { @autowired private productsdao productsdao; @transactional public void addproducts(products products){ productsdao.addproduct(products); } @transactional public list<products> listproducts() { return productsdao.listproducts(); } @transactional public void removeproducts(integer id) { productsdao.removeproducts(id); } }
well, productsserviceimpl class doesn't implement productsservice... there's no way bean injected in field of type productsservice.
