4.Controller调用

@Api("AssociationController")
@RestController
@RequestMapping("/api/association")
public class AssociationController {
	Logger logger = LoggerFactory.getLogger(AssociationController.class);
	@Resource(name = "secondaryJdbcTemplate")
	private JdbcTemplate jdbcTemplate2;
/**
	private static String YQ_Search;
	@Value("${yq_search}")
	public void setYQ_Search(String YQ_Search){
		this.YQ_Search=YQ_Search;
	}**/
}
