spring boot 提交参数绑定List下标越界，超过256，java.lang.IndexOutOfBoundsException异常

springMVC框架提交参数list时，springmvc默认只能接收到255个数据,当你前台传的数据长度大于255位的时候就会报错

错误信息如下：

解决办法

• 在方法所在类加如下代码，这样只改变当前类的配置

   @InitBinder  //类初始化是调用的方法注解
    public void initBinder(WebDataBinder binder) {  
        binder.setAutoGrowNestedPaths(true);
        //给这个controller配置接收list的长度100000，仅在这个controller有效
        binder.setAutoGrowCollectionLimit(10000); 

    }

• 全局更改相应配置

package com.gsww.demo.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.bind.WebDataBinder;
import org.springframework.web.bind.support.ConfigurableWebBindingInitializer;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter;


/**
 * 配置请求集合数组长度
 * @author wuxie
 * @version 2019-5-10
 */
@Configuration
public class MyAppConfig {

    @Autowired
    public MyAppConfig(RequestMappingHandlerAdapter requestMappingHandlerAdapter) {
        requestMappingHandlerAdapter.setWebBindingInitializer(new MyWebBindingInitializer());
    }

    /**
     * 配置请求集合上限数量
     * @author wuxie
     * @version 2019-5-10
     */
    public static class MyWebBindingInitializer extends ConfigurableWebBindingInitializer {

        @Override
        public void initBinder(WebDataBinder binder) {
            super.initBinder(binder);
            binder.setAutoGrowNestedPaths(true);
            //配置集合上限数量
            binder.setAutoGrowCollectionLimit(10000);
        }
    }
}
