java - 更改 QueryDSL 生成的文件目录

Question

我已将 QueryDSL 集成到我的 Spring boot 项目中。

构建.gradle:

//dependencies
compile("com.mysema.querydsl:querydsl-jpa:3.7.4")
compile("com.mysema.querydsl:querydsl-apt:3.7.4:jpa")

idea {
    module {
        sourceDirs += file('src/main/generated/')
        generatedSourceDirs += file('src/main/generated/')
    }
}

生成的.class和.java(Q类)文件当前部署到build/classes/main/my/package/model 创建实体类文件的位置。

如何配置JPAAnnotationProcessor以将生成的源(例如QMyEntity.java)放入src/main/generated？

Answer 1

你可以尝试这样的事情(困难的方式):

def queryDslOutput = file("src/main/generated")
sourceSets {
    main {
        java {
            srcDir queryDslOutput
        }
    }
}

task generateQueryDSL(type: JavaCompile, group: 'build') {
    source = sourceSets.main.java
    classpath = configurations.compile
    destinationDir = queryDslOutput
    options.compilerArgs = [
            "-proc:only",
            "-processor", 'com.querydsl.apt.jpa.JPAAnnotationProcessor,lombok.launch.AnnotationProcessorHider$AnnotationProcessor'
    ]
}
compileJava.dependsOn(generateQueryDSL)

clean {
    delete queryDslOutput
}

如果您使用 lombok，则需要编译器选项。

或者如果您使用 querydsl-plugin您可以配置输出目录(简单的方法):

def generatedClassesPath= "build/generated/source/querydsl/main"

querydsl {
    jpa = true
    querydslSourcesDir = generatedClassesPath
}

您始终可以将生成的源添加到类路径以通过 Intellij Idea 捕获文件:

def queryDslOutput = file(generatedClassesPath)
sourceSets {
    main {
        java {
            srcDir queryDslOutput
        }
    }
}

来自插件文档:

querydslSourcesDir

The project relative path to where the querydsl meta model sources are created in. It does not matter which annotation processors are used, all meta model classes will be created within this directory.

Defaults to src/querydsl/java.
