Springboot无法自动注入JdbcTemplate，非maven

WonHyo 2018-03-22 04:45:41

注意了，我没有用到maven，也没有pom.xml文件。需要的jar包我都是自己导进项目的。
在dao层配置注解



@Repository("wxDao")

public class WxDaoImpl implements WxDao {

	@Autowired	 

	private JdbcTemplate jt;

	

	@Override

	public List<Map<String, Object>> getUserList() {

		// TODO Auto-generated method stub

		String sql="select * from userTable";

		System.out.println("success");

		return null;

	}

}

启动入口类，报错找不到JdbcTemplate的bean，主要报错如下

Description:



Field jt in com.weapp.dao.impl.WxDaoImpl required a bean of type 'org.springframework.jdbc.core.JdbcTemplate' that could not be found.

	- Bean method 'jdbcTemplate' not loaded because @ConditionalOnSingleCandidate (types: javax.sql.DataSource; SearchStrategy: all) did not find any beans





Action:



Consider revisiting the conditions above or defining a bean of type 'org.springframework.jdbc.core.JdbcTemplate' in your configuration.
