FindBugs是看了ss 论坛上YuLimin的提示,技术活干不了,体力活我来扛

FindBugs

这里有两篇介绍用法的文章:

结果

找到 bug 总数 50,这里的bug,只是按照FindBugs默认定义的pattern找到的结果,
不一定是真正的bug,例如
DSL中有6个是因为HistoryEventListener尚未完成,

造成的误报,表格后面列出了详细的位置,请大家有时间核对一下。

代码

详细解释

数量

DSL

Dead store to local variable

This instruction assigns a value to a local variable, but the value is not read by any

 subsequent instruction. Often, this indicates an error, because the value computed is never

 used.

Note that Sun's javac compiler often generates dead stores for final local variables. Because

 FindBugs is a bytecode-based tool, there is no easy way to eliminate these false positives.

8

DM

Method invokes System.exit(...)

Invoking System.exit shuts down the entire Java virtual machine. This should only been done

 when it is appropriate. Such calls make it hard or impossible for your code to be invoked by

 other code. Consider throwing a RuntimeException instead.

1

EI

Method may expose internal representation by returning reference to mutable object

Returning a reference to a mutable object value stored in one of the object's fields exposes

 the internal representation of the object. If instances are accessed by untrusted code, and

 unchecked changes to the mutable object would compromise security or other important

 properties, you will need to do something different. Returning a new copy of the object is

 better approach in many situations.

5

EI2

Method may expose internal representation by incorporating reference to mutable object

This code stores a reference to an externally mutable object into the internal representation

 of the object. If instances are accessed by untrusted code, and unchecked changes to the

 mutable object would compromise security or other important properties, you will need to do

 something different. Storing a copy of the object is better approach in many situations.

8

IJU

TestCase implements tearDown but doesn't call super.tearDown()

Class is a JUnit TestCase and implements the tearDown method. The tearDown method should call

 super.tearDown(), but doesn't.

1

MF

Class defines field that obscures a superclass field

This class defines a field with the same name as a visible instance field in a superclass.

 This is confusing, and may indicate an error if methods update or access one of the fields

 when they wanted the other.

5

MS

Field isn't final but should be

A mutable static field could be changed by malicious code or by accident from another

 package. The field could be made final to avoid this vulnerability.

8

NP

Possible null pointer dereference in method

A reference value dereferenced here might be null at runtime. This may lead to a

 NullPointerException when the code is executed.

2

ODR

Method may fail to close database resource

The method creates a database resource (such as a database connection or row set), does not

 assign it to any fields, pass it to other methods, or return it, and does not appear to close

 the object on all paths out of the method. Failure to close database resources on all paths

 out of a method may result in poor performance, and could cause the application to have

 problems communicating with the database.

2

REC

java.lang.Exception is caught when Exception is not thrown

This method uses a try-catch block that catches Exception objects, but Exception is not

 thrown within the try block, and RuntimeException is not explicitly caught. It is a common

 bug pattern to say try { ... } catch (Exception e) { something } as a shorthand for catching

 a number of types of exception each of whose catch blocks is identical, but this construct

 also accidentally catches RuntimeException as well, masking potential bugs.

1

SIC

Should be a static inner class

This class is an inner class, but does not use its embedded reference to the object which

 created it. This reference makes the instances of the class larger, and may keep the

 reference to the creator object alive longer than necessary. If possible, the class should be

 be made static.

1

SS

Unread field: should this field be static?

This class contains an instance final field that is initialized to a compile-time static

 value. Consider making the field static.

3

UI

Usage of GetResource may be unsafe if class is extended

Calling this.getClass().getResource(...) could give results other than expected if this class

 is extended by a class in another package.

2

UrF

Unread field

This field is never read. Consider removing it from the class.

1

WMI

Inefficient use of keySet iterator instead of entrySet iterator

This method accesses the value of a Map entry, using a key that was retrieved from a keySet

 iterator. It is more efficient to use an iterator on the entrySet of the map, to avoid the

 Map.get(key) lookup.

谢谢兄弟阿,在jira里建个task先:)
虽然粗略看了一下,好像没有真正错误的地方,但还是可以用来做参考把代码改得pretty些:)
等改完了,再PMD一下?  回复  更多评论
