spring - NoSuchBeanDefinitionException despite being defined -

i have beans.xml definition:

<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans"        xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"        xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">         <bean id="products" class="com.example.products">         <property name="products">             <map key-type="java.lang.string" value-type="com.example.product">                 <entry key="coke">                     <bean class="com.example.product">                         <property name="name" value="coke"/>                         <property name="price" value="2.0"/>                     </bean>                 </entry>                 <entry key="crisps">                     <bean class="com.example.product">                         <property name="name" value="crisps"/>                         <property name="price" value="4.29"/>                     </bean>                 </entry>                 <entry key="snickers">                     <bean class="com.example.product">                         <property name="name" value="snickers"/>                         <property name="price" value="1.69"/>                     </bean>                 </entry>                 <entry key="beer">                     <bean class="com.example.product">                         <property name="name" value="beer"/>                         <property name="price" value="3.6"/>                     </bean>                 </entry>              </map>          </property>      </bean>      <bean id="coinverter" class="com.example.coinverter" />   </beans> 

the problem products autowired quite well.

package com.example;  import java.util.collection; import java.util.hashmap; import java.util.map;  /**  * created oneat on 11/5/16.  */ public class products {      public map<string, product> products = new hashmap<>();      products() {      }       public final void add(product p) {         products.put(p.name, p);     }      public void setproducts(map<string, product> products) {         this.products = products;     }      public map<string, product> getproducts() {         return products;     }      public collection<product> toarray(){         return products.values();      }  } 

however coinverter fails on autowiring with

description:

field coinconverter in com.example.fuckingcontroller required bean of type 'com.example.coinverter' not found.

action:

consider defining bean of type 'com.example.coinverter' in configuration.

here src:

package com.example;  import java.util.arrays; import java.util.collections; import java.util.linkedlist; import java.util.list;  /**  * created oneat on 11/6/16.  */ public class coinverter {       public coinverter() {     }      public cointainer arraytocointainer(integer[] i) throws exception {         cointainer ct = new cointainer();         integer[] conv = arrays.copyof(i, i.length);         (int = 0; < conv.length; a++) {             while (conv[a]-- > 0) ct.add(new coin(coin.values[a]));         }         return ct;     }       public integer[] cointainertoarray(cointainer ct) throws exception {         list<integer> li = new linkedlist<>();         coin[] co = coin.returnall();         (coin c : co) {             li.add(collections.frequency(ct.lc, c));         }         return li.toarray(new integer[0]);     }  } 

any idea why happening?

autowiring:

@controller public class fuckingcontroller {      @autowired     coinverter coinconverter;      @autowired     products products;           @requestmapping("/")     public string index(@requestparam(value="yourcoins", required=false) integer[] values, model m) throws exception{          m.addattribute("coins",coin.returnall());         m.addattribute("products", products.toarray());         m.addattribute("coinvalues", products.toarray());           return "index";     } } 

in order make spring's dispatcherservlet pick , load the beans, need add beans.xml web.xml below:

<servlet>         <servlet-name>spring-web</servlet-name>         <servlet-class>                        org.springframework.web.servlet.dispatcherservlet                 </servlet-class>         <load-on-startup>1</load-on-startup>         <init-param>             <param-name>contextconfiglocation</param-name>             <param-value>/web-inf/beans.xml</param-value>             <!-- change xml path correctly if not under web-inf -->         </init-param>     </servlet>
