当在Spring Boot应用程序上禁用视图打开时,Eclipse或Spring Boot可以帮助我找到需要事务的方法吗?

问题描述 投票:0回答:1

[我有一个正在使用的相当新的Spring Boot Java应用程序,但我没有意识到默认情况下没有启用spring jpa“ open-in-view”设置。

我遇到了一些问题,这些问题导致禁用该设置最终是最好的解决方案,但是现在我遇到了一些偶然地依赖它的情况。

例如,我有一个未标记为@Transactions的Service类,在返回到控制器之前,在我的一个实体的惰性初始化子级上进行了循环。

现在,此函数按预期方式引发LazyInitializationException,因为我不在事务中。

我尚未编写可提供100%覆盖率的测试用例,是否可以在Eclipse或Sprint Tools Suite或Spring Boot运行时中内置任何可生成报告的内容,以告诉我何时使用@Entity注释的类在非事务方法调用中对它们进行过函数调用吗?

[尝试以其他方式尝试识别此问题,而无需在我的应用程序中添加100%代码覆盖率测试,还是用细齿梳检查每个方法调用?

如果没有,那么我将处理测试用例。

感谢您的指导。

这并不完美,但是我确实找到了一种使用Reflections库为我的应用程序查找大多数案例的方法。我将其作为@SpringBootTest测试用例运行,并一次修复了一个错误。

@Test
public void testOne() throws NoSuchMethodException, SecurityException{
    Reflections reflections = new Reflections("my.base.package",
                        new SubTypesScanner(), 
                          new TypeAnnotationsScanner(),
                          new MemberUsageScanner());

    Set<Class<?>> annotated = reflections.getTypesAnnotatedWith(javax.persistence.Entity.class);

    for( Class<?> c: annotated){
        log.debug(c.getSimpleName());
        for( Method m: c.getMethods()){
            if( m.getReturnType().isAnnotationPresent(Entity.class) ){
                checkTransactional(reflections,c, m, 0);
            }
        }
    }
   Assert.assertTrue(true);
}

public static void checkTransactional(Reflections reflections, Class<?> c, Method m, int depth) throws NoSuchMethodException, SecurityException{
    if( depth >64){
        throw new RuntimeException("No Transactional Method Found");
        //return;
    }
    String s = "--";
    Annotation t = null;

    Class<?>[] possibleAnnotations = {
            org.springframework.transaction.annotation.Transactional.class,
            javax.transaction.Transactional.class, 
    };

    Annotation[] annotations = m.getAnnotations();
    for( Annotation a: annotations){
        Class<?> aClass = a.annotationType();
        //// handle javax and spring Transactional
        if( aClass.getSimpleName().equals("Transactional")){
            t = a;
            s = "++";
            break;
        }
    }


    String prefix = "";
    for( int i = 0; i < depth; i++){
        prefix = prefix + s;
    }

    log.debug( prefix + " " + c.getCanonicalName() + ":" + m.getName());

    if( t != null ){
        log.trace("This is transactional");
        return;
    }

    Set<Member> callingMembers = reflections.getMethodUsage(m);
    if( callingMembers.size() == 0){
        log.error("Nothing calls this method, if it is a controller, we have a problem" + (c.isAnnotationPresent(Controller.class) || c.isAnnotationPresent(RestController.class)));
        if( (c.isAnnotationPresent(Controller.class) || c.isAnnotationPresent(RestController.class)) ){
            throw new RuntimeException("No transactional method found in call heirrchy before controller"); 
        }
    }
    for( Member usingMember: callingMembers){
        Class<?> callingClass = usingMember.getDeclaringClass();
        List<Method> callingMethods = new ArrayList<Method>();
        if( callingClass != c ){
            for( Method callingClassMethod: callingClass.getMethods()){
                if( callingClassMethod.getName().equals(usingMember.getName())){
                    callingMethods.add(callingClassMethod);
                }
            }   
        }
        if( callingMethods.size() > 2){
            log.error("Two methods call this, manually review");
            for( Method caller: callingMethods){
                log.debug( prefix + "!! " + c.getCanonicalName() + ":" + caller.getName() + ":" + caller.getParameterCount());
            }
            throw new RuntimeException("Two methods with same name ( overloading ) call this, manually review"); 

        }
        for( Method caller: callingMethods){
            checkTransactional(reflections, callingClass, caller, depth+1);
        }
    }
}
