How to link conditional methods in Java 8

I have a spring security configuration method I want a specific method link ant matchers ("/ * * / * *") Permitall() only if the conditions match Such things {dev = = true?. antmatchers ("/ * * / * *"). Permitall(): () – > {}} Of course, this is not an effective grammar. What is the most important thing to do Look for the menimum code

@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();
    }

Solution

The only way is to assign intermediate objects to variables

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();
