如何使用带有多个生成器选项的节俭java代码生成器

Question

我正在查看第三层代码生成器的文档。一开始是这样的：

Usage: thrift [options] file
Options:
  -version    Print the compiler version
  -o dir      Set the output directory for gen-* packages
               (default: current directory)
  -out dir    Set the ouput location for generated files.
               (no gen-* folder will be created)
  -I dir      Add a directory to the list of directories
                searched for include directives
  -nowarn     Suppress all compiler warnings (BAD!)
  -strict     Strict compiler warnings on
  -v[erbose]  Verbose mode
  -r[ecurse]  Also generate included files
  -debug      Parse debug trace to stdout
  --allow-neg-keys  Allow negative field keys (Used to preserve protocol
                compatibility with older .thrift files)
  --allow-64bit-consts  Do not print warnings about using 64-bit constants
  --gen STR   Generate code with a dynamically-registered generator.
                STR has the form language[:key1=val1[,key2,[key3=val3]]].
                Keys and values are options passed to the generator.
                Many options will not require values.

下面是这样的情况：

  java (Java):
    beans:           Members will be private, and setter methods will return void.
    private-members: Members will be private, but setter methods will return 'this' like usual.
    nocamel:         Do not use CamelCase field accessors with beans.
    hashcode:        Generate quality hashCode methods.
    android_legacy:  Do not use java.io.IOException(throwable) (available for Android 2.3 and above).
    java5:           Generate Java 1.5 compliant code (includes android_legacy flag).
    sorted_containers:
                     Use TreeSet/TreeMap instead of HashSet/HashMap as a implementation of set/map.

我完成了这个任务：-java:bean，但我不知道如何包含多个选项。我不明白这意味着什么:语言[：key1=val1[，key2，key3=val3]]

我尝试过这样的方法：“java[：bean，: hashcode]”，“java:bean，hashcode”“java:bean”，“java:bean :hashcode”“java[：bean，hashcode]”等等。

这是标准符号，您会发现在整个地方都有大多数命令行实用工具，甚至是跨平台的。[括号]包含可选参数，方括号本身不在命令行中键入。

因此，在您的例子中，您想要这样做(例如)：

thrift -gen java:beans,private-members,nocamel,java5,sorted_containers  yourfile.thrift

为java生成器指定五个附加选项。一些罕见的选项也采用了值，在这种情况下，它将是(例如，不是真实的)：

thrift -gen java:option1=foo,option2,option3=bar  yourfile.thrift

它传递三个选项，其中两个选项具有关联的值。
