spring boot中使用@RequestBody MultiValueMap 总是报400,415错误
Content-Type为application/json时,报415错误
如下图所示
Content-Type为application/x-www-form-urlencoded时,报400错误
代码结构如下图:
代码如下:
build.gradle
buildscript {
ext {
springBootVersion = '1.4.1.RELEASE'
}
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'spring-boot'
jar {
baseName = 'demo'
version = '0.0.1-SNAPSHOT'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
repositories {
mavenCentral()
}
dependencies {
compile('org.springframework.boot:spring-boot-starter-web')
compile('org.springframework.boot:spring-boot-starter-web-services')
testCompile('org.springframework.boot:spring-boot-starter-test')
}

@SpringBootApplication

public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}

headers: {
'Accept': 'application/json',
// 改为application/json时,会报415错误
'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'

'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8' 问题在这里 'application/x-www-form-urlencoded' 你传送的数据格式为json,但是请求头标志了为application/x-www-form-urlencoded这个,改为'Content-Type': 'application/json' 就可以了,不过会衍生其他问题,在使用cors跨域的时候会出现请求头附带的信息被打包到 request payload 里面.
