spring bean: Bean property 'users' is not writable or has an invalid setter method. Does t

作者:互联网

Bean property 'users' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

错误原因:users作为属性名,写错了,没有匹配上RolesProps的属性名,改成props就没问题了。

<bean id="rolesprops" class="springidol.RolesProps">
        <property name="roleName" value="超级管理props"/>
        <property name="users">
            <props>
                <prop key="USER">王武</prop>
                <prop key="AGE">19</prop>
            </props>
        </property>
        <property name="nullprop"> <null/> </property>
    </bean>

/**
 * Properties注入
 */
public class RolesProps {
    
    private String roleName;
    private Properties props;
    private String nullprop;
    
    
    
    public String getNullprop() {
        return nullprop;
    }
    public void setNullprop(String nullprop) {
        this.nullprop = nullprop;
    }
    public String getRoleName() {
        return roleName;
    }
    public void setRoleName(String roleName) {
        this.roleName = roleName;
    }
    public Properties getProps() {
        return props;
    }
    public void setProps(Properties props) {
        this.props = props;
    }
   

public static void props(){
        ApplicationContext factory = new ClassPathXmlApplicationContext("spring-beanstudy.xml");
        RolesProps obj = (RolesProps) factory.getBean("rolesprops");
        System.out.println(obj.getRoleName());
        System.out.println(obj.getNullprop());
        System.out.println(obj.getProps().get("USER"));
        System.out.println(obj.getProps().get("AGE"));
    }
