Given the function $f(x)=x+ \frac {1+a}{x}-a\ln x(a > -1)$,
(1) Find the monotonic intervals of the function $f(x)$;
(2) If there exists a point $x_{0}$ in the interval $[1,e]$ ($e=2.718…$ is the base of the natural logarithm) such that $f(x_{0}) < 0$ holds, find the range of values of the real number $a$.
