Spring配置bean出现的问题：Does the parameter type of the setter match the return type of the getter?

1、报错信息

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userDao' defined in class path resource [applicationContext.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'jdbcTemplate' of bean class [com.sukoyakaken.dao.impl.UserDaoImpl]: 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?
    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyPropertyValues(AbstractAutowireCapableBeanFactory.java:1642)
    ...

Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'jdbcTemplate' of bean class [com.sukoyakaken.dao.impl.UserDaoImpl]: 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?

    ...

2、applicationContext

    <!--加载jdbc.properties-->
    <context:property-placeholder location="classpath:jdbc.properties"></context:property-placeholder>

    <!--配置数据源对象-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driver}"></property>
        <property name="jdbcUrl" value="${jdbc.url}"></property>
        <property name="user" value="${jdbc.username}"></property>
        <property name="password" value="${jdbc.password}"></property>
    </bean>

    <!--配置JdbcTemplate对象-->
    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource" ref="dataSource"></property>
    </bean>

    <!--配置UserDao-->
    <bean id="userDao" class="com.sukoyakaken.dao.impl.UserDaoImpl">
        <property name="jdbcTemplate" ref="jdbcTemplate"/>
    </bean>

    <!--配置UserService-->
    <bean id="userService" class="com.sukoyakaken.service.impl.UserServiceImpl">
        <property name="userDao" ref="userDao"/>
    </bean>

    <!--配置RoleDao-->
    <bean id="roleDao" class="com.sukoyakaken.dao.impl.RoleDaoImpl">
        <property name="jdbcTemplate" ref="jdbcTemplate"/>
    </bean>

    <!--配置RoleService-->
    <bean id="roleService" class="com.sukoyakaken.service.impl.RoleServiceImpl">
        <property name="roleDao" ref="roleDao"/>
    </bean>

3、controller

@RequestMapping("/user")
@Controller
public class UserController {
    @Autowired
    private UserService userService;

    @RequestMapping("/list")
    public ModelAndView list() {
        List<User> userList = userService.list();
        ModelAndView modelAndView = new ModelAndView();
        // 设置模型
        modelAndView.addObject("userList", userList);
        // 设置视图
        modelAndView.setViewName("user-list");
        return modelAndView;
    }
}

4、service

public class UserServiceImpl implements UserService {
    private UserDao userDao;
    public void setUserDao(UserDao userDao) {
        this.userDao = userDao;
    }

    @Override
    public List<User> list() {
        List<User> userList = userDao.findAll();
        return userList;
    }
}

5、dao

public class UserDaoImpl implements UserDao {
    private JdbcTemplate jdbcTemplate;
    public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
        this.jdbcTemplate = jdbcTemplate;
    }

    @Override
    public List<User> findAll() {
        List<User> userList = jdbcTemplate.query("select * from sys_user", new BeanPropertyRowMapper<User>(User.class));
        return userList;
    }
}

6、补充：
我还有一个RoleController、RoleService、RoleDao，也是按这一套流程写的，就名字和页面不同，但它就可以成功运行，所以应该可以确定环境之类的没有问题。只要加上上面User的代码，tomcat就会报错。求家人们解救！感谢！(T人T)

UserDaoImpl里面加上
private JdbcTemplate jdbcTemplate;
public void setJdbcTemplate(JdbcTemplate jdbcTemplate){
this.jdbcTemplate = jdbcTemplate;
}
其他的dao也同理

代码压缩丢网盘，这个错误有点意思

Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'jdbcTemplate' of bean class [com.sukoyakaken.dao.impl.UserDaoImpl]: Bean property 'jdbcTemplate' is not writable or has an invalid setter method.
错误不都写出来了，问题解决了嘛
