QuerySyntaxException：无法找到类
我正在使用hql生成类JunctionManagementListDto的实际Java对象。 但我最终在我的控制台上遇到以下exception
org.hibernate.hql.internal.ast.QuerySyntaxException: Unable to locate class [JunctionManagementListDto] [SELECT new JunctionManagementListDto(c.siteId, c.name, c.ip, c.customer.id, zm.zone.name) FROM com.traff.hibernate.model.Controllers c, com.traff.hibernate.model.ZoneControllerMapping zm WHERE c.siteId = zm.controller.siteId ] at org.hibernate.hql.internal.ast.QuerySyntaxException.convert(QuerySyntaxException.java:54) at org.hibernate.hql.internal.ast.QuerySyntaxException.convert(QuerySyntaxException.java:47) at org.hibernate.hql.internal.ast.ErrorCounter.throwQueryException(ErrorCounter.java:79) at org.hibernate.hql.internal.ast.QueryTranslatorImpl.analyze(QueryTranslatorImpl.java:255) at org.hibernate.hql.internal.ast.QueryTranslatorImpl.doCompile(QueryTranslatorImpl.java:183) at org.hibernate.hql.internal.ast.QueryTranslatorImpl.compile(QueryTranslatorImpl.java:136) at org.hibernate.engine.query.spi.HQLQueryPlan.(HQLQueryPlan.java:105) at org.hibernate.engine.query.spi.HQLQueryPlan.(HQLQueryPlan.java:80) at org.hibernate.engine.query.spi.QueryPlanCache.getHQLQueryPlan(QueryPlanCache.java:168) at org.hibernate.internal.AbstractSessionImpl.getHQLQueryPlan(AbstractSessionImpl.java:221) at org.hibernate.internal.AbstractSessionImpl.createQuery(AbstractSessionImpl.java:199) at org.hibernate.internal.SessionImpl.createQuery(SessionImpl.java:1735) at com.traff.hibernate.generic.GenericDAOImpl.readListByHql(GenericDAOImpl.java:107) at com.traff.hibernate.daoImpl.JnMgmtLogDaoImpl.getJunctionManagementList(JnMgmtLogDaoImpl.java:29) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.springframework.aop.support.AopUtils.invokeJoinpointUsingReflection(AopUtils.java:317) at org.springframework.aop.framework.ReflectiveMethodInvocation.invokeJoinpoint(ReflectiveMethodInvocation.java:190) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:157) at org.springframework.transaction.interceptor.TransactionInterceptor$1.proceedWithInvocation(TransactionInterceptor.java:99) at org.springframework.transaction.interceptor.TransactionAspectSupport.invokeWithinTransaction(TransactionAspectSupport.java:281) at org.springframework.transaction.interceptor.TransactionInterceptor.invoke(TransactionInterceptor.java:96) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:179) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:207) at com.sun.proxy.$Proxy175.getJunctionManagementList(Unknown Source) at com.traff.service.report.JunctionManagementReportService.prepareStatusList(JunctionManagementReportService.java:37) at com.traff.service.report.JunctionManagementReportService$$FastClassBySpringCGLIB$$472093e1.invoke() at org.springframework.cglib.proxy.MethodProxy.invoke(MethodProxy.java:204) at org.springframework.aop.framework.CglibAopProxy$CglibMethodInvocation.invokeJoinpoint(CglibAopProxy.java:717) ...... 我的hql查询是在JnMgmtLogDaoImpl类中编写的，所有必需的导入都是
public List getJunctionManagementList(String zoneName, Integer customerId) { String hql = "SELECT new JunctionManagementListDto(c.siteId, c.name, c.ip, c.customer.id, zm.zone.name) " +"FROM Controllers c, ZoneControllerMapping zm " +"WHERE c.siteId = zm.controller.siteId "; if(zoneName != "") hql += " and zm.zone.name='"+zoneName+"' "; if (customerId!=null) hql += " and zm.controller.customer.id='"+customerId+"' "; return super.readListByHql(hql); }
和JunctionManagementListDto声明为
public class JunctionManagementListDto {
private String zoneName; private Integer siteId; private String name; private String ip; private Integer customerId; public String getZoneName() { return zoneName; } public void setZoneName(String zoneName) { this.zoneName = zoneName; } public Integer getSiteId() { return siteId; } public void setSiteId(Integer siteId) { this.siteId = siteId; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getIp() { return ip; } public void setIp(String ip) { this.ip = ip; } public Integer getCustomerName() { return customerId; } public void setCustomerName(Integer customerId) { this.customerId = customerId; } public JunctionManagementListDto(Integer siteId, String zoneName, String ip, Integer customerId, String junctionName) { super(); this.siteId = siteId; this.customerId = customerId; this.ip = ip; this.zoneName = zoneName; name = junctionName; } public JunctionManagementListDto(){ } }
导致此exception的原因是什么？如何解决？
我通过指定构造函数的完全限定名称来解决此问题。
public List getJunctionManagementList(String zoneName, Integer customerId) { String hql = "SELECT new (packagename).JunctionManagementListDto(c.siteId, c.name, c.ip, c.customer.id, zm.zone.name) " +"FROM Controllers c, ZoneControllerMapping zm " +"WHERE c.siteId = zm.controller.siteId "; if(zoneName != "") hql += " and zm.zone.name='"+zoneName+"' "; if (customerId!=null) hql += " and zm.controller.customer.id='"+customerId+"' "; return super.readListByHql(hql); }
