使用带有Spring数据JPA的Spring AOP时获取java.lang.IllegalArgumentException

所以我们在这里使用Spring Data JPA来持久化Task对象。需要在TaskRepository save()方法之前和之后运行一个进程。所以我创建了一个方面并使用@Around为切入点分配了advice方法。一切正常，我能够持久保存任务对象，并在save（）方法之前和之后调用通知。 但在我得到的回应中

  

IllegalArgumentException：null source

以下是Aspect代码：

@Aspect
    public class TaskAspect {

        @Autowired
        private TaskRepository taskRepository;

        @Autowired
        private CWFAuditRepository cwfAuditRepository;

        @Pointcut("execution(* com.repository.TaskRepository.save(..)) and target(Task)")
        public void performance(){}

        @Around("performance()")
        public void watchPerformance(ProceedingJoinPoint jp){
            try {
                if(jp.getArgs()[0]!=null && jp.getArgs()[0] instanceof Task){
                    List<CWFAudit> data=null;
                    Task taskObject=(Task)jp.getArgs()[0];
                    Task taskFromDB = (taskObject!=null && taskObject.getId()!=null)?new Task(taskRepository.findOne(taskObject.getId())):null;
                    System.out.println("Thread.currentThread().getName() = "+Thread.currentThread().getName());
                    jp.proceed();
                    if(taskFromDB!=null)
                        compareTasks(taskFromDB, taskObject);
                }
            } catch (Throwable e) {
                e.printStackTrace();
            }
        }
    }

，这是例外：

由于您已经在使用Sprinf数据，我建议您使用Spring Data Auditing来摆脱所有这些麻烦。 它是一个框架，通过在public static class Test { [Table(Name="test_table")] public class TestEntity { [Column(Name = "id", IsPrimaryKey = true, IsDbGenerated = true, CanBeNull = false, DbType = "INT NOT NULL IDENTITY")] public Int32 Id { get; set; } [Column(Name = "name", CanBeNull = false, DbType = "NVARCHAR(20) NOT NULL UNIQUE")] public String Name { get; set; } } [Database(Name = "TestDB")] public class TestContext : DataContext { public Table<TestEntity> Entities { get { return base.GetTable<TestEntity>(); } } public TestContext(IDbConnection connection) : base(connection) { } } public static void TryCreate(string dataSource) { IDbConnection connection; TestContext context; // create connection { SqlCeConnectionStringBuilder stringBuilder = new SqlCeConnectionStringBuilder(); stringBuilder.DataSource = dataSource; connection = new SqlCeConnection(stringBuilder.ConnectionString); } // create context context = new TestContext(connection); // create database if (context.DatabaseExists()) context.DeleteDatabase(); context.CreateDatabase(); } } 提供程序的顶部添加额外的抽象层来扩展JPA，并提供与Spring Security集成等各种开箱即用的功能。

需要在更新记录之前获取以前的数据...   Spring Data Auditing提供了有关谁和何时的详细信息   发生了变化。但要捕获旧数据和新数据等细节   两者，我找不到审核API是友好的

您可以使用Hibernate Envers从您的文档中轻松捕获旧数据和新数据等详细信息：

  

与Subversion类似，该库具有修订的概念。   基本上，一个交易是一个修订（除非交易   没有修改任何被审计的实体）。由于修订是全球性的，   拥有修订号，您可以查询各种实体   修订，检索数据库的（部分）视图   修订。您可以找到具有日期的修订号，另一个   另一方面，您可以获得提交修订的日期。
