Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException:

Question

I was trying to get data from a MySQL database using the Spring utility ResultSetExtractor, but I got the following exception:

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'edao' defined in class path resource [applicationContext2.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'jdbcTemplate' of bean class [org.resultset.EmployeeDao]: Bean property 'jdbcTemplate' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

  List<Employee> list=dao.getAllEmployees();  

  for(Employee e:list)

}

and applicationContext2.xml

<?xml version="1.0" encoding="UTF-8"?>  
<beans  
    xmlns="http://www.springframework.org/schema/beans"  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
    xmlns:p="http://www.springframework.org/schema/p"  
    xsi:schemaLocation="http://www.springframework.org/schema/beans  
 http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">  

<bean id="ds" class="org.springframework.jdbc.datasource.DriverManagerDataSource">  
<property name="driverClassName" value="com.mysql.jdbc.Driver" />  
<property name="url" value="jdbc:mysql://loclahost:3306/test1" />  
<property name="username" value="root" />  
<property name="password" value="" />  
</bean>  

<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">  
<property name="dataSource" ref="ds"></property>  
</bean>  

<bean id="edao" class="org.resultset.EmployeeDao">  
<property name="jdbcTemplate" ref="jdbcTemplate"></property>  
</bean>  

</beans>

These all are java files I am using. It says the setter's return type doesn't match with the getter's, but I checked it, and it is correct there.

The problem is in

<bean id="edao" class="org.resultset.EmployeeDao"> <property name="jdbcTemplate" ref="jdbcTemplate"></property> </bean>

Try changing the name="jdbcTemplate" to name="template". Since you have given name as jdbcTemplate spring will search for a setter method with name setJdbcTemplate() in EmployeeDao class, but the acutal method you have is setTemplate()

Controller extends MethodNameResolver

public final void setMethodNameResolver(
        MethodNameResolver methodNameResolver) {
    this.methodNameResolver = methodNameResolver;
}

public final MethodNameResolver getMethodNameResolver() {
    return this.methodNameResolver;
}

remove spring Annotation like @controller @AutoWired
