弹簧构造函数注入抛出错误

Question

弹簧应用程序我尝试setter注入它运作良好。当我写构造函数注入它失败。

public class Sample { 

    JdbcTemplate jdbcTemplate; 

    public Sample(){ 

    } 

    public Sample(JdbcTemplate jdbcTemplate){ 
     System.out.println("invoked"); 
     this.jdbcTemplate=jdbcTemplate; 
    } 
} 

上下文文件

<bean id="derbyDataSource" 
    class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
    <property name="driverClassName" value="${db.driver}" /> 
    <property name="url" 
     value="jdbc:derby:#{systemProperties['user.appdata']}/${db.name};create=true" /> 
    <property name="username" value="${db.user}" /> 
    <property name="password" value="${db.password}" /> 
</bean> 



<!-- JDBC Template Bean --> 
<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate"> 
    <property name="dataSource" ref="derbyDataSource" /> 
</bean> 



<bean id="sample" class="com.exbury.Sample"> 
    <constructor-arg ref="jdbcTemplate"></constructor-arg> 
</bean> 

负载情况下

ApplicationContext context = new ClassPathXmlApplicationContext("derbyDatabaseConfiguration.xml"); 

错误

Exception in thread "main" java.lang.IncompatibleClassChangeError: class org.springframework.core.LocalVariableTableParameterNameDiscoverer$ParameterNameDiscoveringVisitor has interface org.springframework.asm.ClassVisitor as super class
