thrift - 如何使用带有多个生成器选项的 Thrift Java 代码生成器

Question

我正在查看 thirft 代码生成器的文档。它是这样开始的:

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.

再往下是这样的:

  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.

我得到了这个工作:--gen java:beans，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]]]

我尝试过以下方法:“java[:beans,[:hashcode]]”、“java:[beans,hashcode]”“java[:beans,:hashcode]”“java:beans java:hashcode”“java[:beans[,hashcode]]"等

那就是 standard notation ，您会发现大多数命令行实用程序都具有这种功能，甚至是跨平台的。 [ 括号 ] 包含可选参数，括号本身不在命令行中键入。

所以在你的情况下，你想要这样做(示例):

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。一些罕见的选项也有值，在这种情况下它将是(编造的例子，不是真实的):

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

它传递三个选项，其中两个具有关联的值。
