错误信息:

Error creating bean with name 'accountService3' defined in class path resource [bean.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'java.lang.Object[]' to required type 'java.lang.reflect.Array[]' for property 'myArr'; nested exception is java.lang.IllegalStateException: Cannot convert value of type 'java.lang.String' to required type 'java.lang.reflect.Array' for property 'myArr[0]': no matching editors or conversion strategy found

释意这个样子:使用类路径资源\[bean\]中定义的名称为“accountService3”创建bean时出错。: bean初始化失败;嵌套异常是org.springframe .beans。ConversionNotSupportedException:未能转换“java.lang”类型的属性值。对象\[\]’ to required type ‘java.lang.reflect。数组\[\]‘用于属性’myArr’;嵌套异常是java.lang。\*\*IllegalStateException:不能转换“java.lang”类型的值。字符串“to required type”java.lang.reflect。数组’ for属性’myArr\[0\]’?\*没有找到匹配的编辑器或转换策略

代码处:(源代码)

<bean id="accountService3" class="com.shiyaxin.service.impl.AccountServiceImpl3">
            <property name="myArr">
                <array>  **提示就是这个数组注入错误啦**
                    <value>阿里</value>
                    <value>小龙</value>
                    <value>泰森</value>
                </array>**提示就是这个数组注入错误啦**
            </property>
    对应的类参数位置
    
        private IAccountDao accountDao = new AccountDaoImpl();
        	//只有构造函数是默认的才可以创建，加个参数需要加东西
        //复杂类型的依赖注入,使用set把他们注入进去
        	private Array[]myArr;  **错误我处，错误处  错误处** 数组哪有这个类型Array？
        	private List<String>myList;
        	private Set<String>mySet;
        	private Map<String,String> myMap;
        	private Properties myProp;
        	
            <property name="myMap">
                <map>
                    <entry key="周润发">
                         <value>Hongkong</value>
                    </entry>
                </map>
            </property>

错误解决: private Array\[\]myArr; **错误我处，错误处 错误处** 数组哪有这个类型Array？  
数组换掉这个类型就好了 String INT 都可以的
