Hibernate + Spring (quartz) integration lazy (delayed) loading problem

When the project was developed, the database operation was performed in a job with lazy loading, but the following error

Org.hibernate.LazyInitializationException:failed to lazily initialize a collection of role: ..., no session or Sessio N was closed

Lazy loading is configured in the project using Hibernate annotations, not an XML configuration file,

The following is a list of solutions collected from the Internet

1, report the following error

Org.hibernate.LazyInitializationException:could not initialize Proxy-no Session at

Workaround:

In Web. XML, configure the location of the Springsevlet, using Org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter, with the following code:

<Filter>        <Filter-name>Spring Openentitymanagerinviewfilter</Filter-name>        <Filter-class>Org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</Filter-class>    </Filter>    <filter-mapping>        <Filter-name>Spring Openentitymanagerinviewfilter</Filter-name>        <Url-pattern>/*</Url-pattern>    </filter-mapping>

2, usually in the timed task Quartzjob, or junit test using lazy loading errors, reported the following error

Org.hibernate.LazyInitializationException:failed to lazily initialize a collection of role: ..., no session or Sessio N was closed

Workaround:

Add transaction configuration annotations . The JUnit code is as follows:

@RunWith (Springjunit4classrunner.  Class= {        "File:src/main/webapp/web-inf/applicationcontext.xml",        "file: Src/main/webapp/web-inf/demo-servlet.xml "}) @Transactionalpublicclass  Job {  ...  }

3, there is another way to say is Lazy=false, I again Onetomany | Set fetch= fetchtype in Manytoone annotations. EAGER also does not work, do not know to use the configuration file line not
