How to troubleshoot NPE when "Java" uses @reource or @autowire dependency Injection

The first thing to note is that although both @Resource and @autowire are used for dependency injection annotation, there are differences.1 resource does not depend on spring, the latter is the opposite, so as far as possible to reduce, use resource;2 Resource is preferred to match by variable name, and @resource (name= "") can also be used to specify the variable name to inject. Autowire is preferred by type, with @qualifier can also specify variable name.3 There is no supernatural event! There

Nullpoinerexception (NPE)

line, we create an instance of the integer type and assign it to num, so now that NUM can finally point it out. You can then use this pointer to manipulate the object (. operation). However, if we declare a variable (a reference type) without an assignment statement, we use the variable directly, as follows: Object obj = null; System.out.println (Obj.tostring ()); That's the problem, so the obj variable is like a headless fly and doesn't know where to point. And you call Obj.tostring () is act

How to set breakpoints for programs with Tau G2 in VxWorks

The simulation function of the Tau G2 program itself is very powerful. If a logic error occurs when the program runs on the target machine, you can always simulate this error in the simulation environment of Tau G2 and find the cause of the error, generally, you do not need to use the C code debugging tool of the operating system. However, if a C-language function is called in Tau

Bitstring and octetstring in Tau G2

Tau G2 has more predefined classes than common UML tools, such as bitstring and octetstring. These classes correspond to ASN.1, mainly to facilitate the processing of PDU encoding, which is designed for communication protocol software development. We generally like to use the bitstring class because it is more convenient and intuitive. However, a small problem recently encountered is that when processing long PDU strings using the bitstring class, it

The G2 support problem occurs when streambox Ripper transfers RM to MP3.

Using streambox RIPPER (many websites have small green software for ease of use), you can Files are converted to MP3 files, but generally realpalyer 10 and streambox RIPPER are installed. When an error occurs, you need to install an antique called RealPlayer G2. Otherwise, the conversion will fail. Do it yourself: In general, the prompt for installing realpaly G2 is as follows: Decoding of the file

Definitions and differences of curve smoothing metrics C0, C1, C2, G0, G1, and G2 [z]

the same tangent direction at the connection point. However, to measure smoothness Based on Parameter continuity, the same length of the tangent modulus must also be consistent with that of C1. Therefore,Parameter continuity is an over-limit on the smooth connection of parameter curves and is imposed manually.Parameter continuity is related to parameter selection and specific parameterization. Objective and internal geometric features of the shape, such as smoothness, are independent of paramet
