PasswordEncoder mapped for the id "null" - spring

Question

I use xml configuration in the spring security when I go to the authorization page, I should be thrown to the main page but I get this error:
my login page:
I use data storage in the db
<bean id="myDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="org.postgresql.Driver"/>
<property name="url" value="jdbc:postgresql://localhost:5432/java_a_from_z?useSSL=false"/>
<property name="username" value="postgres"/>
<property name="password" value="root"/>
</bean>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<property name="dataSource" ref="myDataSource"/>
<property name="packagesToScan" value="com.demo"/>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQL9Dialect</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
</bean>
<bean id="myTransactionManager"
class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<tx:annotation-driven transaction-manager="myTransactionManager"/>
my spring-security.xml:
<http auto-config="true">
<intercept-url pattern="/list" access="ROLE_USER"/>
<intercept-url pattern="/security" access="isAnonymous()"/>
<form-login login-page="/security"
login-processing-url="/security"
default-target-url="/list"
authentication-failure-url="/security?error"
username-parameter="username"
password-parameter="password"/>
<logout logout-success-url="/security?logout"/>
<csrf disabled="true"/>
</http>
<authentication-manager>
<authentication-provider>
<user-service>
<user name="user" password="password" authorities="ROLE_USER"/>
</user-service>
</authentication-provider>
</authentication-manager>
<beans:bean id="encoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder"/>
I tried using in my code NoOpPasswordEncoder and BCryptPasswordEncoder. But it does not work.
what needs to be changed in my code?

Answer 1

I added the following to my code:
<authentication-manager>
<authentication-provider>
<user-service>
<user name="user" password="$2a$10$BHjEcnhAgqRH0Vj6aPmGTOtQfYdx3PsvTWjsVxVBouiLTzGSLTSz2" authorities="USER"/>
</user-service>
<password-encoder ref="encoder" />
</authentication-provider>
</authentication-manager>
<beans:bean id="encoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder"/>
and now everything works
