【问题描述】:
我是 spring mvc 的新手,我刚刚开始了一个基于 java 配置的项目 在构建我的项目时,我从 Tomcat 日志中收到了这条消息:
SEVERE: Context initialization failed
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'countryController': Unsatisfied dependency expressed through field 'countryService'; nested exception is org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'countryService' is expected to be of type 'com.djamel.service.CountryService' but was actually of type 'com.sun.proxy.$Proxy37'
这是我的 CountryService 课程:
@Service
public class CountryService implements Services<Country>{
@Autowired
CountryDao countryDao;
@Autowired
CityDao cityDao;
...
@Transactional
public Long add(Country country) {
Long key = countryDao.add(country);
if(!country.getCities().isEmpty()){
for (City city : country.getCities()) {
cityDao.add(key, city);
}
}
return (long) 1;
}
...
}
这是我的配置类:
@Configuration
@EnableWebMvc
@EnableTransactionManagement
@ComponentScan(basePackages = "com.djamel")
public class AppConfig {
@Bean
public DataSource dataSource() {
...
}
@Bean
public JdbcTemplate jdbcTemplate(DataSource dataSource) {
...
}
}
请问,我该如何解决这个问题?

请在此处发布 CountryService 类代码。我认为您尚未在该类上添加 @Service 注释。请发布代码以获得更好的分辨率。
