小编tpl*_*cht的帖子

我有以下代码片段,我想知道是否以及如何用Streams/Java 8 API替换它

for (State state : states) {
    for (City city : cities) {
        if (state.containsPoint(city.getLocation())) {
            System.out.printf("%30s is part of %-30s\n",
                    city.getName(), state.getName());
        }
    }
}

我正在使用Spring Boot 1.3.X并具有以下内容:

@RestController
@RequestMapping(path = "/foo")
public class FooController {

    @RequestMapping(method = RequestMethod.GET, params = { "fooBar" })
    public Collection<Entry> firstFoo() {
        //Do something
    }

    @RequestMapping(method = RequestMethod.GET, params = { "anotherFooBar" })
    public Collection<Entry> secondFoo() {
        //Do something other
    }

}

哪个按预期工作.传递错误的参数时,会引发以下异常:

{
    "error": "Bad Request", 
    "exception": "org.springframework.web.bind.UnsatisfiedServletRequestParameterException", 
    "message": "Parameter conditions \"fooBar\" OR \"anotherFooBar\" not met for actual request parameters: elementalFormulae={C11}", 
    "path": "/foo", 
    "status": 400, 
    "timestamp": 1455287433961
}

然后我创建了ExceptionHandler如下所示:

@ControllerAdvice
public class ExcptionController {

    @ResponseStatus(value=HttpStatus.BAD_REQUEST, reason="Invalid …

我们的spring-boot项目如下所示

project
|__ build.gradle
|__ settings.gradle
   |__ module_a
   |__ module_b
   |__ ...
|__ module_a
|__ module_b

module_a仅包含SpringApplication类和文件application.properties

运行./gradlew build工作正常,但问题是,对于每个模块(大约10)gradle生成一个包含所有依赖项的胖jar.

我们想要只有一个远罐(在模块a中)

buildscript {
    ext {
        springBootVersion = '1.2.0.RELEASE'
        springLoadedVersion = '1.2.0.RELEASE'
    }
    repositories {
        // NOTE: You should declare only repositories that you need here
        mavenCentral()
        maven { url "http://repo.spring.io/release" }
        maven { url "http://repo.spring.io/milestone" }
        maven { url "http://repo.spring.io/snapshot" }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        classpath("org.springframework:springloaded:${springLoadedVersion}")
    }
}


allprojects {

    group = "example.group"
    version = "0.0.1"

    repositories() {
        mavenCentral()
    }

} …
