NoSuchBeanDefinitionException至少1 Bean上有资格作为自动装配候选人

我有问题，Spring框架，我正在寻找解决方案很长一段时间，但是任何结果。

当我部署一个应用程序，我得到异常：

这里是一个UserDAOImpl，其中注入的DataSource

@Component
public class UserDaoImpl implements UserDao {

    private JdbcTemplate template;

    @Override
    public List&lt;User&gt; findAll(){
        return template.query(Sql.SQL_QUERY_FIND_ALL ,new UserRowMapper&lt;User&gt;());
    }

    @Override
    public User fintById(long id){
        return template.queryForObject(Sql.SQL_QUERY_FIND_BY_ID,  new Object[]{id}, new UserRowMapper&lt;User&gt;());
    }

    @Override
    public void create(final User user){
        KeyHolder keyHolder = new GeneratedKeyHolder();
        PreparedStatementCreator psCreator = new PreparedStatementCreator() {
            @Override
            public PreparedStatement createPreparedStatement(Connection connection) throws SQLException {
                PreparedStatement stmt = connection.prepareStatement(
                Sql.SQL_QUERY_SAVE, Statement.RETURN_GENERATED_KEYS);
                stmt.setString(1, user.getFirstName());
                stmt.setString(2, user.getLastName());
                stmt.setString(3, user.getEmail());
                return stmt;
            }
        };

        template.update(psCreator, keyHolder);
        user.setId(keyHolder.getKey().longValue());
    }

    @Override
    public void delete(User user){
        template.update(Sql.SQL_QUERY_DELETE, new Object[]{ user.getId() });
    }

    @Autowired
    @Qualifier("dataSource")
    public void setDataSource(DataSource dataSource){
        template = new JdbcTemplate(dataSource);
    }        
}

问题解决了。我必须包括在beans.xml到XX-servlet.xml中的配置。

该setter注入不正确应用。在春天，你不能把新的运营商。考虑setter和构造器注入。这里是setter注入的一个例子...试试这个：

@Repository
public class UserDaoImpl implements UserDao {

@Autowired
private JdbcTemplate template;

public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
      this.jdbcTemplate = jdbcTemplate;
}

@Override
public List<User> findAll(){
    return this.template.query(Sql.SQL_QUERY_FIND_ALL ,new UserRowMapper&lt;User&gt;());
}

@Override
public User fintById(long id){
    return this.template.queryForObject(Sql.SQL_QUERY_FIND_BY_ID,  new Object[]{id}, new UserRowMapper&lt;User&gt;());

}

@Override
public void create(final User user){
  ...
}

@Override
public void delete(User user){
    this.template.update(Sql.SQL_QUERY_DELETE, new Object[]{ user.getId() });
}

的DbContext：

<jdbc:embedded-database id="dataSource" type="DERBY">
    <jdbc:script location="classpath:create-schema.sql"/>
</jdbc:embedded-database>

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

对于存储库/ DAO类使用@ 程序存储库的注释，而不是@Component。确保基础扫描的DAO类启用，因此Spring可以找到并注入他们。您不必明确定义bean与@Service，@Repository和@Controller注解xml文件将被注入。

<context:component-scan base-package="com.something.dao"/>

希望帮助。
