如何在Java 8中进行条件方法链接

我有一个 spring security配置方法.我想要一个特定的方法链接antMatchers(“/ ** / **”).permitAll()仅在条件匹配时.这样的事情{dev == true？ .antMatchers(“/ ** / **”).permitAll():() – > {}}.当然,这不是一个有效的语法,最重要的做法是什么.寻找menimum编码.

@Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .csrf().disable()
            .cors().disable()
            .authorizeRequests()
            {dev == true ? .antMatchers("/**/**").permitAll(): ()->{}} //dev only. NEVER enable on prod 
                .antMatchers("/","/signup","/static/**","/api/sigin","/api/signup","**/favicon.ico").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/")
                .loginProcessingUrl("/api/signin")
                .successHandler(authSuccessHandler())
                .failureHandler(authFailureHandler())
                .permitAll()
                .and()
            .logout()
                .permitAll();
    }

WhateverAuthorizeRequestsReturns partial = http
    .csrf().disable()
    .cors().disable()
    .authorizeRequests();

if (dev) // note: you don't need 'dev == true' like you had
{
    partial.someOptionalThing();
    // if the type is immutable then you need to reassign e.g.:
    // partial = partial.someOptionalThing()
}

partial.something()
    .somethingElse()
    .andTheRest();
